-S-

S-bar deletion
SYNTAX: deletion of the S-bar node of an embedded complement clause. This operation has been proposed to account for the transparency exhibited in the case of °Exceptional Case Marking and °Subject Raising. °CP-reduction.
LIT. Chomsky (1981).

Schwa
PHONOLOGY: a vowel often described as a mid central unrounded vowel of brief duration. Phonetic symbol is [@]. EXAMPLE: the final vowel in koper 'copper'.
LIT. Halle & Clements (1983).

Schwa insertion
PHONOLOGY: °epenthesis of °schwa between two consonants. EXAMPLE: Dutch melk 'milk' may be pronounced as [mel@k].

Scope
SEMANTICS: that part of a °formula to which an operator is prefixed. EXAMPLE: phi is the scope of Neg in Neg phi and of All(x) in All(x) [ phi ]. The scope of an operator in complex formulas is determined by brackets. In the formula in (i) the subformula P(x) -> Q(y) is the scope of All(x), but R(x) is outside the scope of All(x).

(i) All(x) [ P(x) -> Q(y) ] & R(x)
LIT. Gamut (1991).
SYNTAX: It is usually assumed that for those syntactic elements which are interpreted as elements with scope (e.g. NPs such as everyone and who, which are interpreted as (quantificational) operators), the scope assigned to the element that is the interpretation of the syntactic element is determined as a function of the syntactic context of the syntactic element. It has often been assumed, furthermore, that the notion °c-command plays a crucial role in the determination of the scope of (the interpretation of) quantificational and other scopal elements. Thus, May (1977) states that "the scope of a quantifier phi is everything which it c-commands" (meaning: at LF). Thus, if the relevant syntactic level of representation where scope is determined is the level of LF (which is denied, e.g., by Williams (1986)) then which LFs can be derived from a given S-structure determines the possible scopal orders of the scopal elements in the structure (°scope ambiguity, °QR).
LIT. May (1977, 1985, 1989).

Scope ambiguity
SYNTAX/SEMANTICS: the kind of ambiguity that arises when an operator can enter into different scope relations with other scoped elements. EXAMPLE: (i)a has the two readings (i)b and c. In (ib) every farmer is construed as having scope over a donkey and in (ic) a donkey is construed as having scope over every farmer:

(i) a  Every farmer loves a donkey
    b  For every farmer there is a donkey such that he loves him
    c  There is a donkey such that every farmer loves him
LIT. Montague (1974), May (1977).

Scrambling
SYNTAX: cover term for specific kind of word order variation. In the study of Germanic SOV-languages the term is used to refer to word order variation of argument NPs with respect to each other and/or with respect to adverbial phrases. EXAMPLE: in German an object may follow or precede an adverb (object and adverb may be scrambled):

(i)    a  Er hat ihr vielleicht dieses Buch gegeben
	  he has her maybe      this   book given
       b  Er hat ihr dieses Buch vielleicht gegeben
Two objects may be scrambled as well:
(ii)	  Er hat dieses Buch vielleicht ihr gegeben
And sometimes an object - den Max in (iii) - may even scramble over the subject, as in (iii)b:
(iii)  a  ... dass jeder den Max kennt
	      that everyone (the) Max knows
       b  ... dass den Max jeder kennt
It seems that °definiteness is a factor interfering with scrambling. Nonspecific indefinite NPs cannot be scrambled and neither can particles or small clause predicates. One point of controversy is whether scrambling is a case of movement (of NP) and if so whether it is °A-bar movement or not.
LIT. Ross (1967), Webelhuth & den Besten (1987), Webelhuth (1989), Grewendorf & Sternefeld (1990), Neeleman (1994).

S-dominate
°dominate.

Segment
PHONOLOGY: °phoneme.
SYNTAX: structural/configurational notion. In an °adjunction structure like (i), the category A consists of two segments, the upper A and the lower A.

(i)		A
	       /|
	      /	|
	     B	A
Cf. °Exclusion, °Dominance.
LIT. Chomsky (1986b), Lasnik & Saito (1991).

Selection
°Subcategorization.

Selectional restrictions
SEMANTICS: the semantic restrictions that a word imposes on the environment in which it occurs. EXAMPLE: a verb like eat requires that its subject refers to an animate entity and its object to something concrete. A violation of the selectional restrictions of a word results in °anomaly: in the mountain eats sincerity both restrictions are violated, rendering the sentence anomalous. The question whether selectional restrictions should be treated in syntax or semantics, or even outside grammar, as a matter of knowledge of the world, has been a point of debate.
LIT. Chomsky (1965).

Self-dual
°Dual.

Semantic Coherence
MORPHOLOGY: a notion introduced in Aronoff (1976) which entails that the meaning of a derivative is transparently a composition of the meaning of the base and that of the affix. EXAMPLE: all English words of the form Xousness mean:

(i)	'the fact that Y is Xous'
(ii)	'the extent to which Y is Xous'
(iii)	'the quality or state of being Xous'
Hence, the meaning of Xousness words is fully compositional in meaning. This is not true for rival words of the form Xosity which have additional idiosyncratic meanings.
LIT. Aronoff (1976), Spencer (1991).

Semantic component
That part of grammar which contains the rules that provide syntactic structures with a °semantic interpretation.

Semantic compositionality
MORPHOLOGY: we speak of semantic compositionality if the meaning of a complex word is a function of the meanings of its constituents. EXAMPLE: the meaning of English °gerunds is fully compositional ('the state, action named by V').

Semantic interpretation
SEMANTICS: the process by which syntactic structures are associated with their meaning. This can be done in terms of a °semantic representation or in terms of values in a model. When taken as a result nominal, the term 'semantic interpretation' is used synonymously with °semantic representation.
LIT. Chierchia & McConnell-Ginet (1990).

Semantic reference
°Speaker's reference.

Semantic representation
SEMANTICS: an abstract (formal) language in which meanings can be represented. Opinions differ about whether semantic representation is sufficient or necessary, about its form and about how it relates to syntactic representations. Mentalistic, representational theories of meaning claim that a mental semantic representation is necessary to account for the fact that language users grasp meanings. Denotational theories of meaning, on the other hand, claim that meaning can only be explicated in terms of denotations in the world. Semantic representation can take the form of a structure of semantic features (in the °Katz-Fodor-semantics and in Jackendoff's °conceptual structure) or formulas of a logical system. In the theory of °Generative semantics, semantic representations were identified with syntactic deep structures. In almost all other theories, semantic representations are an autonomous level of representation related to deep structure, surface structure and/or LF. See °meaning theories.
LIT. Chierchia & McConnell-Ginet (1990), Jackendoff (1983).

Semantic role
°Thematic role.

Sense
SEMANTICS: the sense (German: Sinn) of an expression is, according to Frege (1892), the way in which its °reference (German: Bedeutung) is presented. EXAMPLE: the sentences (i) and (ii) both have the same truth value (i.e. the same reference), but differ in sense.

(i)  The Morning Star is the Evening Star
(ii) The Morning Star is the Morning Star
See °intension and °extension.
LIT. Frege (1892), Gamut (1991).

Sentential Subject Constraint
SYNTAX: one of the constraints on movement proposed by Ross (1967). It states that

	No element dominated by an S may be moved out of that S if that S 
        is dominated by an NP which itself is immediately dominated by S,
and is meant to capture the fact that categories cannot be moved out of a sentential subject. EXAMPLE: consider (i) and (ii), both containing a sentential subject (the for-clause and the that-clause respectively).
(i)  [for Haarhuis to beat Becker] is easy
(ii) [that Haarhuis beat Becker] pleased us
The Sentential Subject Constraint now correctly predicts that wh-movement of Becker out of the sentential subject leads to ungrammaticality:
(i')  *	Who is [for Haarhuis to beat t] easy?
(ii') *	Who did [that Haarhuis beat t] please us?
The Sentential Subject Constraint falls under the °Subject Condition of Huang's (1982) °Condition on Extraction Domain.
LIT. Ross (1967).

Separation Hypothesis
MORPHOLOGY: a hypothesis due to Robert Beard, which entails that the form of inflectional and derivational affixes is separated from their function. Beard distinguishes L-rules and M-rules, and assumes that L-rules are grammatical processes which change or add information about grammatical functions (e.g. 'plural' or 'agent noun'), while M-rules are affixation rules which spell out the grammatical functions. EXAMPLE: English plurals are formed in a number of ways, as is shown in (i):

(i) cat-cats, bus-busses, alga-algae, paramecium-paramecia, goose-geese
Under the separation hypothesis there is a single L-rule of pluralization which simply adds the feature [plural]. The resulting abstract morpheme is input to different M-rules, and these rules spell out the actual phonological form of the plurals in (i). On the other hand, °conversion can be seen to be simply the situation which arises when an L-rule applies, but no M-rule gets the chance of giving phonological content to the function supplied by the L-rule.
LIT. Beard (1982, 1987, 1988), Sproat (1985), Ackema & Don (1992), Don (1993).

Shape Component
MORPHOLOGY: a component in the grammar proposed in the work of Arnold Zwicky. This component contains the lexicon, together with separate sets of inflectional rules and derivational rules. Moreover, this component houses the Shape Conditions which govern the selection of different allomorphs postlexically, that is, in the syntax. EXAMPLE: the distribution of the English a/an allomorphs (a book vs. an apple) is handled by a Shape Condition.
LIT. Zwicky (1977, 1986, 1987).

Signifiant
°Signification

Signification
SEMANTICS: the structuralist notion for being a sign, i.e. the property of expressions that they stand for other things. A sign is viewed as a composite unit consisting of a relation between an overt signal (the signifier) and the information that this overt signal evokes (the signified). The notions 'signifier' and 'signified' are also known as (French) 'signifiant' and 'signifié' from De Saussure (1959). See °Denotation, °Reference.
LIT. Lyons (1977), Frawley (1992).

Signifié
°Signification.

Simple determiner
SEMANTICS: a simple determiner is a determiner which is not a boolean combination of two or more determiners. EXAMPLE: at least two and at most four are simple determiners; at least two and at most four is not a simple determiner.
LIT. Gamut (1991).

Singular
°Number.

Sister
SYNTAX: two °nodes A and B are sisters iff there is a node C (their mother) which °immediately dominates both A and B.

Sisterhood Condition
SYNTAX: condition on °theta-role assignment which requires the theta-marker and the target of theta-marking to be °sisters. This condition is proposed in Chomsky (1986b).

Sloppy identity
SYNTAX: an interpretive phenomenon found in °deletion contexts. If part of a syntactic structure is not overtly realized, and has its interpretation determined as a copy of the interpretation of a constituent elsewhere in the structure or in the discourse, and if the structure whose interpretation is copied into the covert constituent contains an anaphoric element whose interpretation depends on an element not contained in the copied material, then the anaphor's counterpart in the copy may either have the same reference as the original, or pick up an (anaphoric) reference independently. The former case is called "strict identity", the latter case "sloppy identity". EXAMPLE: Consider (i):

(i)     Johni [VP likes hisi mother ], and Peter too
The missing VP in the right conjunct is interpreted as a copy of the VP in the left conjunct. However, two distinct interpretations may result:
(ii) a  Johni [VP likes hisi mother ], and Peterj too 
        [VP likes hisi mother ]

     b  Johni [VP likes hisi mother ], and Peterj too 
        [VP likes hisj mother ]
The b-interpretation is a case of sloppy identity: the index on his is not identical. Syntactic conditions on sloppy identity have been argued to mirror conditions on °bound variable anaphora (Reinhart 1983).
LIT. Sag (1976), Williams (1977), Partee (1978), Reinhart (1983).

Sluicing
SYNTAX: reducing a wh-question to its wh-phrase(s) in a context where the omitted part can be reconstructed from the preceding sentence. EXAMPLE: in (i) the content of the complement clause of know is understood as which sonata's Susan has played.

(i) Susan has played some sonata's, but I don't know which sonata's __
Sentences like (i) raise the question whether there is an °empty category following which sonata's, and if so, how it is °licensed.
LIT. Ross (1969).

Small Clause
SYNTAX: subject-predicate construction without a finite verb. EXAMPLE: the PP in (i) and the NP in (ii) are analyzed as small clauses with him the subject.

(i)  I want [PP him out of my sight]
(ii) They consider [NP him a fine teacher]
In general a small clause is an XP with a subject, where X = N, A, V or P. It is a point of debate whether the subject is in the °specifier position of XP, or adjoined to XP at D-structure.
LIT. Stowell (1983), Hoekstra & Mulder (1990).

Sole Argument Generalization
MORPHOLOGY: a generalization proposed in Levin & Rappaport (1986) which says that an argument that may stand as a sole NP complement to a verb can be externalized by Adjectival Passive Formation. This generalization is meant to account for the difference between (ii) and (iii):

(i)	Dick sold Tom the car.
(ii)	The car remained unsold.
(iii)  *Tom remained unsold.
In (ii), the internal argument of sell is externalized. This is allowed since the NP the car can be the sole argument of sell (cf. Dick sold the car). In (iii), on the other hand, the second internal argument of sell is externalized, but this NP cannot be the sole argument (cf. *Dick sold Tom in the reading Dick sold something to Tom), and externalization therefore is not possible.
LIT. Levin & Rappaport (1986), Spencer (1991).

Sonorant
PHONOLOGY: a °feature which characterizes sounds that are produced in such a way that the vocal cords vibrate spontaneously (i.e. °vowels, °glides, °liquids and °nasals).

Sonority
PHONOLOGY: a perceptual property referring to the loudness (audibility) and propensity for spontaneous voicing of a sound relative to that of other sounds with the same length.

Sonority hierarchy
PHONOLOGY: a hierarchy representing the °sonority of classes of sounds. Cf. Katamba (1989) (refinements can be added):

least sonority                              greatest sonority
voiceless obstruents    voiced obstruents    nasals    glides    vowels
The sonority hierarchy can be used, to explain distributions of segments in syllables. The °nucleus (i.e. vowel) of a syllable is the most sonorous element. The sonority of the surrounding consonants must decrease to the left and to the right starting from the vowel. Put differently: the more sonorous a segment, the closer to the nucleus of the syllable. EXAMPLE: in English the syllables matl, lkon are impossible since in matl the sonority in the sequence tl increases (must be: decreasing) and in lkon the sonority of the sequence lk decreases (must be increasing).
LIT. Kiparsky (1979), Selkirk (1980).

Source
SEMANTICS: one of the possible °thematic roles of a verb, indicating the place or object where the movement expressed by the verb starts. EXAMPLE: in John received a book from Mary Mary is the source of the movement of the book (the °theme) to John (the °goal).
LIT. Fillmore (1968), Gruber (1965), Jackendoff (1983, 1990).

Speaker's reference
SEMANTICS: the reference that a noun phrase has in virtue of what the speaker chooses it to be, as distinguished from the semantic reference, that it has in virtue of its meaning. Kripke (1977) argued that °referential and °attributive noun phrases have the same semantic reference but possibly different speaker's references.
LIT. Kripke (1977).

Specific reading
SEMANTICS: the reading that an indefinite noun phrase has when there is a particular referent of that noun phrase. In the sentence John seeks a unicorn, a unicorn has a specific reading when there is a particular unicorn that John is looking for. This reading entails the existence of unicorns in the domain of discourse. A unicorn has a nonspecific reading when John is looking for an arbitrary unicorn. This does not entail the existence of unicorns. The specificity-contrast is often analyzed in terms of the relative scope of the indefinite with respect to an °opaque context. The specific reading, then, corresponds with the °wide scope (or de re) reading, while the nonspecific reading corresponds with the °narrow scope (or de dicto) reading.

Specificity Condition
SYNTAX: condition on movement which states that movement out of °specific NP's leads to worse results than movement out of non-specific NP's. This is shown by the contrast in (i) (showing wh-movement out of a definite NP) and (ii) (wh-movement out of a non-specific indefinite NP). Also known as Specificity Constraint.

(i)  a	 *who did you see [that picture of t]
     b	 *who did you see [John's picture of t]
(ii) a	  who did you see [three pictures of t]
     b	  who did you see [more pictures of t]
LIT. Chomsky (1973, 1986b), Fiengo & Higginbotham (1981).

Specified Subject Condition (SSC)
SYNTAX: condition introduced in Chomsky (1973) which states that:

(i)    No rule can involve X, Y in the structure 
       ... X ... [a ... Z ... -WYV ... ] ...
       where Z is the specified subject of WYZ in a
Informally, a subject is specified if it is overt. Therefore, the reciprocal each other can be bound by the men in (ii), but not in (iii):
(ii)	The men saw [NP the pictures of each other]
(iii)  *The men saw [NP John's pictures of each other]
The specified subject John in (iii) blocks the binding relation between the men and each other. In later work, the SSC is subsumed under the °binding theory.
LIT. Chomsky (1973, 1980, 1982).

Specifier
SYNTAX: in terms of the °X-bar theory the specifier is the position which is directly dominated by the maximal projection of X: [XP specifier X]. Many different functions are being assigned to this position, depending on the category of X, such as Determiner of NP, degree element of AP, subject of IP, or modifier (adverb or even auxiliary) of VP. (One version of) the VP-internal Subject Hypothesis holds that Spec,VP is the D-structure position of the verb's external argument. In many analyses of movement ( °bounding theory), the specifier position plays an important role as an intermediate landing site (or °escape hatch) for °A-bar movement.
LIT. Chomsky (1986b).

Specifier-Head agreement
SYNTAX: notion introduced in Chomsky (1986b) to describe the sharing of °phi-features between the head and the specifier of IP. In later work (cf. Chomsky (1991)) the domain of spec-head agreement has been extended to °functional categories other than IP. See °Agreement.

Speech act
SEMANTICS: what a speaker does in uttering a sentence. According to Austin (1962), when uttering a sentence, a speaker is involved in three different speech acts: a locutionary act, an illocutionary act and a perlocutionary act. The locutionary act is the act of uttering a sentence with a certain meaning. The speaker also may intend to constitute a certain act of praise, criticism, threat etc., which is called the illocutionary act (not to be confused with °illocutionary force). The perlocutionary act is the act of trying to bring about a certain change in the addressee (e.g. making him/her believe something). The last type of act is linguistically not relevant. Within a truth-conditional approach, only the locutionary act is seen to be relevant with respect to the °truth conditions.
LIT. Austin (1962), Lyons (1977), Chierchia & McConnell-Ginet (1990).

Speech time
SEMANTICS: the time of utterance of a sentence relative to which tenses are interpreted. In Reichenbach's theory of tense the speech time is represented by a time point S. The °reference time and °event time are ordered with respect to S.
LIT. Reichenbach (1947), Gamut (1991).

Spell-out
SYNTAX: (minimalist theory) instruction to switch to PF. After Spell-out no lexical material can be inserted.
LIT. Chomsky (1992).

Split antecedent
SYNTAX: antecedent which consists of more than one NP. EXAMPLE: in:

(i) Peter proposed to Mary [PRO to have dinner together]
°PRO refers to both Peter and Mary. It is said that PRO has the two NPs Peter and Mary as a split antecedent.
LIT. Williams (1980), Chomsky (1981).

Split-Morphology Hypothesis
MORPHOLOGY: hypothesis which entails that derivation and inflection are distinct, and belong to separate components of the grammar. Derivation is handled by lexical rules, while (regular) inflection is handled by syntactic rules. The Split-Morphology Hypothesis has been endorsed by Anderson (1977, 1982, 1988ab) Scalise (1984, 1988), and Perlmutter (1988).

S-selection
SYNTAX: the conditions which a °head imposes on its immediate context through its °argument structure, i.e. the °theta-roles it assigns, is called s(emantic)-selection. EXAMPLE: the fact that the verb to persuade selects a subject denoting an actor (or °agent), and two complements, one denoting the person who is the action's target and one denoting a proposition (cf. he persuaded me to go), is considered a matter of s-selection. S-selection is distinguished from c(ategorial)-selection, the conditions imposed in terms of categorical features (e.g. N,V). It is a point of debate whether and to what extent c-selection can be derived from s-selection (e.g. by rules of canonical structural realization). Next to s- and c-selection, some assume m(orphological)-selection, which applies word-internally.
LIT. Pesetsky (1982), Chomsky (1986a), Chomsky & Lasnik (1992), Ouhalla (1990).

S-structure
SYNTAX: level of representation derived from °d-structure by °transformational rules, and input to the rules deriving °PF and °LF. S-structure is the °T-model equivalent of °surface structure in the °Standard theory. S-structure is putatively defined by conditions such as the °subjacency condition.
LIT. Chomsky (1981).

Stage
SEMANTICS: a model-theoretic entity, introduced in Carlson (1977), which represents the manifestation of an object or kind in time and space (a 'spatiotemporal slice'). The subjects in (i)a refer to stages of the object John and the kind dog, respectively, to which a transient, temporary predicate applies.

(i)  a	John was running
     b	dogs were running
A stage level interpretation is distinguished from an individual level interpretation: in (ii) John and dogs refer to an object and a kind rather than a spatiotemporal instance.
(ii) a	John is intelligent
     b	dogs are smarter than cats
LIT. Carlson (1977).

Standard theory (ST)
The theory of grammar proposed in Chomsky (1965).

State
°Aspectual classes.

Stem
MORPHOLOGY: a term which is commonly used for the uninflected part of a word. EXAMPLE: if we take the plural form disagreements, the form disagreement is called the stem. In languages such as Ancient Greek, in which words belong to different declensional or conjugational classes (marked by a theme or extension), the stem includes these extensions. For example, Ancient Greek declension I nouns are formed by adding the vowel a to the root géphur+a- 'bridge', while declension II nouns are formed by adding the vowel o to the root hípp+o- 'horse'. The inflectional endings for case and number are added to these forms. Traditionally, the forms géphura- and hippo- are called stems, while géphur- and hipp- are called °roots.

Stranding

Stratum

Stray adjunction
PHONOLOGY: a universal convention by which °extrametrical units are incorporated into the representation of stress. By convention the extrametrical unit is weak. EXAMPLE: in English the final syllable of a noun is extrametrical. After foot construction and word tree construction, the extrametrical syllable is incorporated into the adjacent foot as a weak member by stray adjunction.

	                 
                          /\

         | /\          |  /\ |
         w s w         w s w w    
         | | |         | | | 
	 ameri<ca>  -> america    
LIT. Liberman & Prince (1977), Hayes (1981)).

Strength
SEMANTICS: a property of °determiners and °generalized quantifiers in °Generalized Quantifier Theory. An NP is positive strong if and only if its denotation (a set of sets) always contains the denotation of the CN (common noun). An NP is negative strong if and only if its denotation never contains the denotation of the CN. An NP which is neither positive nor negative strong is called weak. Sentences of the form in (i) provide a test for strength of a determiner D:

(i)   [S [NP DET CN] is a CN/are CN's]
If the sentence is true in every model, D is positive strong (Every dog is a dog); if it is false in every model, D is negative strong (Neither dog is a dog); and if it is true depending on the domain, D is weak (At least two dogs are dogs is only true if there are at least two dogs in the domain E). The distinction between strong and weak determiners can be used to account for the contrast in (ii)-(iv) (due to the °definiteness restriction).
(ii)   *There is every dog in the garden.
(iii)  *There is neither dog in the garden.
(iv)    There are at least two dogs in the garden.
Also °weak and °strong noun phrases.
LIT. Barwise & Cooper (1981), Zwarts (1981), Gamut (1991).

Stress lowering convention
°Stress subordination principle.

Stress neutral affix
PHONOLOGY/MORPHOLOGY: a term which refers to one of the most characteristic properties of °Class II affixes: the property of not having any effect on the stress pattern of the base. EXAMPLE: if we add the affix -ness to the word prodúctive, the stress is unaffected (prodúctiveness). Stress neutral affixes are distinguished from °stress shifting affixes.
LIT. Chomsky & Halle (1968), Siegel (1974).

Stress shifting affixes
PHONOLOGY/MORPHOLOGY: a term which refers to one of the most characteristic properties of °Class I affixes: the property of having effect on the stress pattern of the base. EXAMPLE: if we add the affix -ity to the word prodúctive, the suffix attracts stress to the syllable immediately preceding it (productívity). Stress shift to the last syllable of the base is a prone characteristic of this type of affixes. Stress shifting affixes are distinguished from °stress neutral affixes.
LIT. Chomsky & Halle (1968), Siegel (1974).

Stress subordination principle
PHONOLOGY: a universal convention proposed by Chomsky & Halle (1968) in the linear analysis of stress assignment. In this analysis stress assignment rules assign the °feature [1stress] to vowels. The operation of subsequent stress rules is subject to stress lowering in the following way (Chomsky & Halle (1968:17)):

When primary stress is placed in a certain position then 
all other stresses in the string under consideration at that 
point are automatically weakened by one.
EXAMPLE: Consider the assignment of stress in the °compound black-board. The main stress rule applies in a °cyclic fashion, reassigning [1stress]; the previously assigned [1stress] is weakened to [2stress] by stress lowering:
	  1      1           1    2
	black + board -->  black board

Strict c-command
°C-command.

Strict Cyclicity
PHONOLOGY: A rule may apply to a string x just in case either of the following holds:

 a. The rule makes crucial reference to information in the 
    representation that spans the boundary between the current 
    cycle and the preceding one.

 b. The rule applies solely within the domain of the previous cycle but 
    crucially refers to information supplied by a rule operating on the 
    current cycle. (formulation of Kenstowics (1994))
From this condition on the application of cyclic rules important theoretical consequences have been drawn. It follows form this condition that cyclic rules can not operate on underived lexical items. EXAMPLE: in English the rule Trisyllabic shortening shortens the underlying vowel of sane [e] to [æ] in the derived word san-ity. This rule does not apply in the underived item nightingale.
LIT. Mascaró (1976), Halle (1978), Kiparsky (1985).

Strict subcategorization
SYNTAX: °subcategorization of heads (in particular V) in terms of the phrasal categories (NP, PP, etc.) which they select as a complement. Sometimes strict subcategorization is equated with °c-selection.
LIT. Chomsky (1965, 1986a).

Strident
PHONOLOGY: a °feature which characterizes sounds that are produced with a complex constriction forcing the air stream to strike two surfaces, producing high-intensity fricative noise. Only fricatives and affricates are [+strident].
LIT. Halle & Clements (1983).

Strong crossover
SYNTAX: one kind of °crossover. Occurs in configurations in which a wh-element or quantificational NP undergoes A-bar movement across a pronominal which c-commands the extraction site, as in (i):

(i) *Whoi did hei see ti
Who is moved across he in (i). The fact that he cannot be °coindexed with ti (which would yield the reading: which x, x saw x), is referred to as 'strong crossover', because on the intended reading the structure is strongly ungrammatical. Since the wh-trace, being a °variable, must be °A-free, binding by he would constitute a °Condition C violation. To be distinguished from °weak crossover.
LIT. Postal (1971), Wasow (1972), Chomsky (1976, 1981, 1982).

Strong feature
SYNTAX: (minimalist theory) feature which must be checked in overt syntax.
LIT. Chomsky (1992).

Strong Lexicalist Hypothesis
°Lexicalist Hypothesis.

Strong noun phrase
SEMANTICS: a noun phrase that is excluded (by the °definiteness restriction) as the subject of a °there-insertion sentence. The term was introduced by Milsark (1977) to cover both ordinary definite noun phrases like the boy, but also proper names, pronouns, and quantified noun phrases like every boy and most boys. Milsark (1977) characterizes strong noun phrases as noun phrases that can not be existentially quantified by there, either because they are proper names or pronouns or because they are already quantified (by the, those, every etc.).
LIT. Milsark (1977).

Strong verb
MORPHOLOGY: a term which is used for the class of verbs where inflection is expressed by stem allomorphy or °ablaut, that is, by a change of the stem vowel, a change of the stem consonants, or both. EXAMPLE: English: sing:sang:sung, dwell:dwelt:dwelt, and bring:brought:brought, Dutch: loop:liep:gelopen, zit:zat:gezeten.

Structural ambiguity
SEMANTICS: °ambiguity that arises from the fact that two or more different syntactic structures can be assigned to one string of words. The expression old men and women is structurally ambiguous because it has the following two structural analyses:

(i)  old [men and women]
(ii) [old men] and women
Ambiguous expressions that are not structurally ambiguous are °lexically ambiguous.

Structural case
SYNTAX: °case which is assigned in a certain structural configuration, depending on government (and adjacency) only (as opposed to °inherent case). EXAMPLE: it has been proposed that a verb assigns structural Accusative case to its NP complement, and that Nominative case is assigned by the finite inflection (°INFL) to the canonical subject position [NP,IP]. More recently, structural case is identified with case assignment to the specifier in a specific kind of AGRP.
LIT. Chomsky (1986a, 1991).

Structure-building rule
PHONOLOGY/MORPHOLOGY: a rule which does not change already specified information. This rule just fills in information which is unspecified. EXAMPLE: the feature [voice] is distinctive within the class of obstruents, but non-distinctive in the class of sonorants. The latter fact can be expressed by leaving [voice] unspecified for this class of sounds. In the course of a derivation [voice] can be filled in by a structure-building rule. A property of structure-building rules is that the input and output are non-distinct.
LIT. Kiparsky (1982), Archangeli (1984).

Structure-changing rule
PHONOLOGY/MORPHOLOGY: a rule which changes already specified information, and renders the output form distinct from the input. EXAMPLE: the feature [voice] is distinctive within the class of obstruents, but non-distinctive in the class of sonorants. If there is a rule which devoices obstruents in a particular environment, say word final, this rule will be structure-changing if it changes [-son, +voice] into [-son, -voice].
LIT. Kiparsky (1982), Archangeli (1984).

Structure preservation
MORPHOLOGY/PHONOLOGY: a property of (lexical) rules which entails that they cannot introduce segments which are not otherwise motivated as underlying phonological segments of the language. EXAMPLE: the underlying sound inventory of Dutch does not contain voiceless sonorants, but it does contain voiced and voiceless obstruents. Furthermore, Dutch has a rule of final devoicing, but characteristically this rule does not effect sonorants. Hence, the rule of final devoicing is structure preserving.
LIT. Aronoff (1976), Kiparsky (1982, 1985).
SYNTAX: a rule or rule system is structure preserving if its output is independently available as an underlying (underived) structure. The hypothesis that natural language grammars are structure preserving has first been elaborated in Emonds (1970), and is taken for granted in much ongoing work.

Structure-preserving Constraint
SYNTAX: principle which states that a moved constituent may only be substituted for a category of the same type. EXAMPLE: this principle prevents an NP from being moved to a °V-position.
LIT. Emonds (1976), Radford (1981).

Subcategorization
SYNTAX/MORPHOLOGY: a concept by which differences in syntactic valency between words is expressed. EXAMPLE: a transitive verb has to be followed by a direct object NP contrary to intransitive verbs. We can say that transitive verbs form a subcategory of the category of verbs, by virtue of the fact that they must be followed by an NP complement. It is the obligatory presence of the object which gives rise to the subcategory of transitive verbs. The object subcategorizes the verb, or the verb is subcategorized by the object.
LIT. Chomsky (1965), Van Riemsdijk & Williams (1987), Spencer (1991).

Subcategorization frame
SYNTAX/MORPHOLOGY: a formalization of the notion of °subcategorization. EXAMPLE: (i) gives the (°strict) subcategorization frame of the verb hit. It says that the pseudo-transitive verb hit optionally (indicated by the parentheses) selects an NP-complement (a sister-node, as indicated by the square brackets) to its right (indicated by the order '__ NP' rather than 'NP __').

(i) hit: [ __ (NP)]
Also see °s-selection.
LIT. Chomsky (1965, 1986a), Van Riemsdijk & Williams (1987), Spencer (1991).

Subcategorization insertion
°Lexical transformation.

Subjacency
°Bounding theory.

Subject
SYNTAX: The subject of a sentence is the category that occupies the specifier position of IP ([Spec, IP]), or some other designated phrase and which in finite clauses °agrees with the finite verb. Furthermore, if a verb assigns an agent-role and it is not a passive verb, the agent-role is associated with the subject. Also, if nominative case is assigned, it is assigned to the subject. Stowell (1983) has proposed that all lexical phrase may contain a subject, presumably in the specifier position (e.g. John in John's attempt).
LIT. Chomsky (1970, 1981), Stowell (1983).

SUBJECT
SYNTAX: the subject of an infinitive, an NP or a small clause is a SUBJECT, as well as INFL (AGR) of a finite clause. This notion of SUBJECT is invoked to entail that AGR of a finite clause creates a °governing category, and that NP is a governing category only if it has a subject (e.g. John's story about himself).
LIT. Chomsky (1981).

Subject Condition
SYNTAX: one of the °Conditions on Extraction Domains, stating the impossibility of extraction from subjects. EXAMPLE: this condition accounts for the ill-formedness of (i) and (ii), where who and what are extracted from the subject of the complement sentence.

(i)  *	I wonder who [IP [books of t] are on the table]
(ii) *	I wonder what [IP [reading t] would be boring]
LIT. Huang (1982), Chomsky (1986b).

Subject control verb
SYNTAX: if the subject of a verb °controls the reference of the °PRO subject of its infinitival complement, the verb is called a subject control verb. EXAMPLE: promise in (i)a is a subject control verb (PRO must be coreferential with John), but the verb order in (i)b and force in (i)c are not (they are °object control verbs).

(i) a  Johni promised mej [PROi/*j to go away]
    b  Johni ordered mej [PRO*i/j to go away]
    c  Johni forced mej [PRO*i/j to go away]

Subject Raising
SYNTAX: movement of the subject of a sentential complement to the subject position of the matrix clause. EXAMPLE: in (i) John, the subject of to have won has moved to the subject position of seems.

(i)  Johni seems [ ti to have won ]
Subject Raising is triggered by Subject Raising verbs (e.g. to seem), which have as a characteristic property that they do not assign an °external theta-role, and select a sentential complement with a case-less subject position. Subject Raising also occurs with passivized °ECM verbs, as in (ii).
(ii) Johni is considered [ ti to have won ]
LIT. Chomsky (1981).

Subject Restriction
MORPHOLOGY: a constraint proposed in Selkirk (1982) which says that the subject argument of a lexical item may not be satisfied in compound structure. This constraint is meant to account for the observation that the subject (or external argument) of a verb cannot function as the non-head in a °synthetic compound. EXAMPLE: next to the sentence the girl swims we do not find the synthetic compound *girl-swimming.
LIT. Roeper & Siegel (1978), Selkirk (1982), Spencer (1991).

Subjunctive
SYNTAX: mode of tense, different from indicative, used in embedded clauses and indicating that the information expressed in the clause is non-factive. EXAMPLE: the verb être in French has soit in (ii) as a subjunctive form, distinct from the indicative form est in (i).

(i)  Je sais qu'il est capable
     I know that he isIND capable
(ii) Il faut qu'il soit capable
     It must that he beSUBJ capable
     'He should be capable'

Substitution
SYNTAX: the movement of a category alpha to an empty position beta such that beta is replaced by alpha. It is one of two possible formats of movement rules, the other being °adjunction. If alpha and beta are non-distinct, substitution is a °structure preserving operation.

Substitution salva veritate
SEMANTICS: the possibility of replacing an expression alpha by an expression beta with the same reference in such a way that the resulting sentence has the same truth-value. EXAMPLE: given that Beatrix is the eldest daughter of Juliana sentence (i)a is equivalent to (i)b in which the eldest daughter of Juliana has been substituted for Beatrix. Hence the substitution is salva veritate.

(i) a  Beatrix lives in The Hague
    b  The eldest daughter of Juliana lives in The Hague
Substitution salva veritate is not possible in °opaque contexts.
LIT. Gamut (1991).

Subtractive morphology
MORPHOLOGY: a term which refers to the situation where the semantically more complex category is represented by a phonologically simpler form. EXAMPLE: the genitive plural of feminine and neuter nouns in -a/-o in Russian (kniga 'book', mesto 'place') are formed without any (overt) affixation (knig, mest).
LIT. Scalise (1984), Spencer (1991).

Suffix
MORPHOLOGY: a °bound morpheme (or °affix) which attaches at the righthand side of a base. EXAMPLE: the English morpheme -ness is a suffix, since it attaches to the right of adjectives (productiveness).

Super raising
SYNTAX: construction in which a subject position is skipped in applying °Subject Raising. The result is ungrammatical. EXAMPLE: next to (i), which is an ordinary case of subject raising, (ii) is impossible, since the subject position taken by it is skipped in moving Vitesse to the subject position of seems.

(i)   Vitesse seems [t to win]
(ii) *Vitesse seems [that it is certain [t to win]]
LIT. Chomsky (1981, 1986b).

Superiority
SYNTAX: °node alpha is superior to node beta iff alpha °c-commands beta, but beta does not c-command alpha.

Superiority condition
SYNTAX: condition on the application of transformations, which states that, if a transformation can in principle be applied to two constituents in the structure, it has to be applied to the one that is °superior. The formal definition (from Chomsky (1973)) is as follows:

 No rule can involve X,Y in the structure ...X...[...Z...-WYV...]...
 where the rule applies ambiguously to Z and Y and Z is superior to Y
EXAMPLE: given that °wh-movement can apply only once in deriving the °s-structure of a sentence, the superiority condition predicts that in structure (i) what cannot be moved: who is superior to what. The contrast in (ii) shows this prediction to be correct.
(i)		S'
	       / \
 	     COMP S
                 / \
	       NP   VP
               |   / \
	      who V   NP
	          |   |
	         saw what


(ii) a	 (I wonder) who saw what
     b	*(I wonder) what who saw
LIT. Chomsky (1973, 1986b, 1992), Lasnik & Saito (1991).

Superlative
MORPHOLOGY: an inflectional form which is characteristic of adjectives, and which opposes to the °positive and °comparative. If we take the English morphs long-longer-longest, the first one is the positive form, the second the comparative and the third the superlative.

Suppletion
MORPHOLOGY: a phenomenon by which the addition of a semantic aspect or grammatical function is expressed by a totally or partially different morpheme which has little or no phonological connection with the base form. EXAMPLE: the alternation between the English verb go and its past tense form went is an example of total suppletion. The alternation between France and French is an example of partial suppletion.
LIT. Spencer (1991).

Surface structure
SYNTAX: syntactic structure derived from °Deep structure by means of °transformational rules. Also °S-structure.
LIT. Chomsky (1981).

Syllabic
PHONOLOGY: a °feature used in the linear framework of Chomsky & Halle (1968), which characterizes sounds that function as syllabic °nuclei; non-syllabic sounds occur at syllable margins.

Syllabification
PHONOLOGY: the division of a word in °syllables in conformity with universal and language-specific requirements (e.g. °Maximal Onset Principle, °sonority hierarchy).

Syllable weight
PHONOLOGY: a property of °syllables, referring to the quantity or internal structure of syllables. Syllables can be divided into light and heavy depending on language-specific requirements (in some languages also superheavy syllables are distinguished). Initial consonants of syllables are irrelevant to quantity. Depending on language-specific requirements there can be an opposition between short and long vowels: V and VC group together as light as opposed to VV which is heavy. Another distinction commonly found is that between a short vowel (light) and VV/VC (heavy). Superheavy are VVC and VCC in languages that distinguish light/heavy/superheavy. Syllable weight plays a determining role in the distribution of stresses in °Quantity-Sensitive stress systems. Heavy syllables generally attract stress regardless of their position in the word. Light syllables are stressed only according to their position in the word. There are at least two approaches to formalizing the concept of syllable weight. In theories of syllabic constituency the heavy/light distinction can be characterized as branching vs. non-branching °nucleus or °rhyme. The other approach, moraic theory, assumes °moras. The distinction light/heavy is made on the basis of mora count. Segments are assigned one mora or two: light syllables are monomoraic and heavy syllables are bimoraic. The two types of representation can be illustrated, for example, in a language that makes a distinction between V (light) and VC/VV (heavy):

 	Syllabic constituency         Moraic theory
	   light:   heavy:            light:     heavy:
	
	   rhyme    rhyme              m         m   m
	
	     V      V  V               V         V   V
	            V  C                         V   C
LIT. Hayes (1981), Hyman (1985), Prince (1983), Van der Hulst (1984), McCarthy & Prince (1986), Hayes (1989).

Syncope
PHONOLOGY: the °deletion of a segment in a word. EXAMPLE: in Dutch [a:k@l@g] -> [a:kl@g] 'nasty'.

Syncretism
MORPHOLOGY: the phenomenon by which a single (inflected) form corresponds to more than one morphosyntactic description. EXAMPLE: in Ancient Greek, the nominative and vocative of the feminine singular/plural case forms are identical (e.g. khóoraa 'a land', khôoraa 'O, land', khôoray 'lands', khôoray 'O, lands'). The same is true for the nominative and accusative of the neuter singular/plural case forms: dôoron 'house-nom./acc.sg.', dôora 'house-nom./acc.pl.'.

Synonymy
SEMANTICS: relation between two words or phrases with the same meaning, like gift and donation.

Syntactic atom
MORPHOLOGY/SYNTAX: term introduced in Di Sciullo & Williams (1987) to refer to the property of words that they are the indivisible building blocks of syntax. Words are atomic with respect to syntax, since syntactic rules or principles cannot make reference to their parts (°lexical integrity).

Synthetic compound
MORPHOLOGY: a particular type of °compound, viz. compounds whose head is derived from a verb by affixation, and where the non-head fulfills the function of argument or complement of the verb. EXAMPLE: the English compounds truck driver, truck driving, fast acting and pan fried are synthetic compounds. Synthetic compounds have played a major role in the development of linguistic theory, since they raise a number a questions concerning the morphology-syntax interface. Another term for synthetic compound is verbal compound.
