Sentences and Meaning: Syntax, Semantics and Pragmatics
2. X-bar theory and the sub-modules: theta, case and binding
X-bar theory generalises phrase structure: every phrase is a projection of a head X, with the schema X′ → X (Complement), XP → (Specifier) X′. So a verb's object is its complement, a determiner or subject can sit in the specifier, and adjuncts adjoin at the X′ level. This captures the endocentric fact that every phrase has a head of the same category (an NP is headed by N, a VP by V).
- Theta theory: a predicate assigns semantic roles (theta-roles such as Agent, Theme, Goal, Experiencer) to its arguments. The Theta Criterion requires each argument to bear exactly one theta-role and each theta-role to be assigned to exactly one argument.
- Case theory: nominals must receive abstract Case (nominative from finite tense, accusative from a transitive verb); the Case Filter rules out an overt NP without Case, explaining why subjects of non-finite clauses behave specially.
- Binding theory governs coreference: Principle A — an anaphor (reflexive/reciprocal) must be bound within its local domain (John saw himself); Principle B — a pronoun must be free in that domain (John saw him, him ≠ John); Principle C — an R-expression (a name) must be free everywhere.
3. Argument structure and valency alternations
A predicate's argument structure lists the arguments it requires and their roles. Valency is the number of arguments a verb takes: sleep is intransitive (one argument, the sleeper), read transitive (two: reader and thing read), give ditransitive (three: giver, recipient, thing given). Valency alternations systematically change this: the passive demotes the subject and promotes the object (The meal was cooked); the causative adds an agent (melt → make something melt); the dative alternation reshapes a ditransitive (give Mary a book ↔ give a book to Mary); the inchoative/anticausative drops the causer (The vase broke).
The syntax-morphology interface shows here: causatives and passives may be marked by morphology on the verb in many languages, and agreement realises syntactic features morphologically. The syntax-semantics interface links structure to meaning — argument positions map to theta-roles, and scope of quantifiers and negation depends on structural height.
4. Syntactic theories, Universal Grammar and competence
| Framework | Core idea | Associated with |
|---|---|---|
| Generative / Minimalist Programme | Structure built by Merge; economy and interface conditions at LF and PF | Noam Chomsky |
| LFG (Lexical Functional Grammar) | Parallel c-structure (constituency) and f-structure (grammatical functions) | Bresnan & Kaplan |
| HPSG (Head-driven Phrase Structure Grammar) | Signs as typed feature structures combined by unification; lexically driven | Pollard & Sag |
Universal Grammar (UG) is the hypothesis that humans are born with an innate blueprint for language — the shared principles underlying all languages — which solves the logical problem of language acquisition: children acquire a rich grammar quickly from limited, imperfect input (the poverty of the stimulus). In the principles-and-parameters version, universal principles are fixed while parameters are set by exposure. Chomsky distinguishes core grammar (the UG-determined system) from a periphery of idioms, borrowings and exceptions, and tacit (implicit) knowledge of the grammar from explicit knowledge about it. Linguistic theory in this programme aims at competence and at explanatory adequacy.
5. Semantics: compositionality, truth, relations and quantifiers
The principle of compositionality (commonly associated with Frege) says the meaning of a complex expression is determined by the meanings of its parts and the way they are combined — which is why we understand sentences we have never heard. In truth-conditional semantics, to know the meaning of a declarative sentence is to know its truth conditions (what the world must be like for it to be true); the sentence expresses a proposition, which is the bearer of truth or falsity. Basic logic adds quantifiers (all, some, no), whose scope interacts with negation and with each other.
- Lexical relations: synonymy (near-identical sense, big/large); antonymy of several kinds — gradable (hot/cold, with a scale between), complementary/binary (alive/dead, where not-one entails the other), and converse/relational (buy/sell, parent/child); hyponymy (rose is a hyponym of flower); meronymy (part-whole, finger/hand).
- Propositional relations: entailment — if A is true B must be true (John killed the wasp entails The wasp died); paraphrase — mutual entailment (same truth conditions); contradiction — A and B cannot both be true; these are tested by truth conditions, not by context.
6. Pragmatics: speech acts, implicature, presupposition and deixis
Pragmatics studies meaning in context — what speakers do and imply beyond literal content. In speech act theory, J. L. Austin distinguished the locutionary act (saying something), the illocutionary act (the force: promising, ordering, asserting) and the perlocutionary act (the effect on the hearer); John Searle developed a taxonomy of illocutionary acts and felicity conditions. Deixis is reference that depends on the utterance context: person (I, you), place (here, there), time (now, tomorrow), plus discourse and social deixis. Discourse analysis studies how sentences cohere into larger connected texts.
H. P. Grice's Cooperative Principle and its four maxims — Quantity (be as informative as required, no more), Quality (be truthful), Relation/Relevance (be relevant) and Manner (be clear, brief, orderly) — explain conversational implicature: meaning inferred when a speaker observes or deliberately flouts a maxim. Asked whether a colleague is a good philosopher, replying "He has very neat handwriting" flouts Quantity/Relation and implicates that he is not. Presupposition is background taken for granted by an utterance (the King of France presupposes such a king exists) and, unlike implicature, is triggered by specific words and survives negation.
7. Analysing syntax across languages, and the interfaces
Syntactic analysis across languages asks how different languages realise the same grammatical relations, and it separates universal principles from parametric choices. The same diagnostics (movement, substitution, agreement, binding) are applied to each language, and the differences are then stated as parameter settings.
- Basic word order: English is SVO, while Hindi–Urdu, Japanese and Tamil are SOV and Welsh is VSO.
- Alignment: in a nominative–accusative language the subject of an intransitive verb patterns with the transitive subject; in an ergative–absolutive language it patterns with the transitive object. Hindi is split-ergative: in the perfective of a transitive verb the agent takes the marker ne and the verb agrees with the (unmarked) object, as in Raam ne kitaab paṛhii.
- Wh-questions: English moves the question word to the front (What did you read?), whereas Hindi typically leaves it in place (tumne kyā paṛhā?), so whether wh-phrases move overtly is a parameter.
- Null subjects: Hindi, Spanish and Italian allow a subject pronoun to be dropped because verb agreement or context identifies it, whereas English requires an overt subject.
Two interfaces complete the picture. At the syntax-phonology interface, prosodic phrasing and intonation are aligned with, though not identical to, syntactic constituents, so a pause or pitch break can signal the bracketing of an ambiguous string such as old men and women. At the semantics-pragmatics interface, the literal (semantic) content of some is 'at least one', but hearers usually take it to mean 'some but not all'. This scalar implicature is generated by the maxim of Quantity, and because it is pragmatic it can be cancelled: Some of the students passed, in fact all did.
Key takeaways
- Sentences are hierarchies of constituents stated by phrase-structure rules and detected by movement, pro-form substitution, coordination and standalone tests. Structural ambiguity is one string with two bracketings (old men and women; PP attachment), distinct from lexical ambiguity.
- X-bar: every phrase projects from a head (XP → Spec X′, X′ → X Comp). Sub-modules: theta theory (Theta Criterion, one role per argument), case theory (Case Filter), binding (A: anaphor bound locally; B: pronoun free locally; C: name free), all stated over c-command.
- Valency is the argument count: sleep 1, read 2, give 3. Valency alternations: passive (demote subject), causative (add agent), dative alternation, inchoative (drop causer). Argument positions map to theta-roles at the syntax-semantics interface.
- Frameworks: generative/Minimalist (Merge, interfaces) — Chomsky; LFG (c-structure + f-structure) — Bresnan & Kaplan; HPSG (unified feature structures) — Pollard & Sag. Universal Grammar answers the poverty of the stimulus; core versus peripheral grammar, tacit versus explicit knowledge, competence as the goal. Typology: English is SVO and Hindi SOV; Hindi is split-ergative (ne); wh-movement and null subjects are parameters.
- Compositionality (Frege): meaning of the whole from the parts and their combination. Truth conditions define propositional meaning; lexical relations include synonymy, gradable/complementary/converse antonymy, hyponymy, meronymy; propositional relations include entailment, paraphrase (mutual entailment) and contradiction.
- Pragmatics: Austin's locutionary/illocutionary/perlocutionary acts and Searle's taxonomy; Grice's Cooperative Principle with maxims of Quantity, Quality, Relation and Manner, implicature arising from flouting; presupposition survives negation; deixis (person, place, time) is context-dependent reference. Scalar implicature ('some' implies 'not all') is pragmatic, so it is cancellable.

A phrase-structure rule such as S → NP VP primarily states which of the following?
Show answer
Answer: A — That a sentence consists of a noun phrase followed by a verb phrase as its immediate constituents
The rule says S has two immediate constituents, an NP and a VP, capturing hierarchy rather than a flat list. Sentences need not contain a PP, and syntax does assign structure; the rule is about constituency, not about computing meaning first.Which test result correctly shows that 'the old book' is a single constituent in 'She read the old book'?
Show answer
Answer: D — It can be replaced by the pro-form 'it' and can stand alone as the answer to 'What did she read?'
Pro-form substitution (it = the old book) and standing alone as an answer are classic constituency diagnostics, and both pick out the whole NP. Rearranging letters is not a syntactic test; 'old' alone is not a constituent here; replacing only 'book' with 'it' does not target the phrase as a unit.In X-bar theory, the object of a verb occupies which position?
Show answer
Answer: B — The complement position, as a sister of the head verb
Under the schema X′ → X Complement, the object is the complement, a sister of the head verb inside V′. The specifier hosts elements like subjects or determiners, adjuncts attach at the X′ level, and the head position is the verb itself.Which statements about the sub-modules of syntax are correct? Select all that apply.
Show answer
Answer: A — The Theta Criterion requires each argument to bear exactly one theta-role; B — Binding Principle A requires an anaphor such as a reflexive to be bound within its local domain; C — Case theory's Case Filter rules out an overt noun phrase that lacks Case
The Theta Criterion, Principle A and the Case Filter are all stated correctly. Principle C is the opposite of the false option: an R-expression (a name) must be free, so it may not be bound by a c-commanding pronoun.In the sentence 'He admires John's paintings', can 'he' and 'John' refer to the same person, and why?
Show answer
Answer: C — No, because 'he' c-commands 'John', and Principle C requires the name to be free
The subject 'he' c-commands 'John' (inside the object NP), and Principle C requires an R-expression like 'John' to be free, so they cannot corefer. Coreference is governed by c-command, not by linear precedence, so the 'comes before' reasoning is wrong; and a reflexive would be ungrammatical here as the subject.In the sentence 'She gave him a book', how many arguments (counting the subject) does the verb give take? Give your answer as a whole number.
Numerical answer — type the value.
Show answer
Answer: 3
Give is ditransitive, with three arguments: the giver ('she', Agent), the recipient ('him', Goal) and the thing given ('a book', Theme). Counting only the two objects and forgetting the subject gives the wrong answer 2; the correct count is 3.The phrase 'old men and women' is structurally ambiguous. How many distinct structural readings does it have? Give your answer as a whole number.
Numerical answer — type the value.
Show answer
Answer: 2
There are two bracketings: [old [men and women]], where 'old' modifies the whole coordination so both groups are old, and [[old men] and women], where 'old' modifies only 'men' so the women need not be old. Two structures means two readings.Which pairing of a syntactic framework with the scholars most associated with it is correct?
Show answer
Answer: A — Lexical Functional Grammar (LFG) — Joan Bresnan and Ronald Kaplan
LFG was developed by Joan Bresnan and Ronald Kaplan. HPSG is Pollard and Sag's, the Minimalist Programme is Chomsky's, and LFG is certainly not Chomsky's work alone, so the other options swap the names.A child acquires a complex grammar rapidly despite hearing limited and imperfect data that underdetermines the adult system. In the generative tradition this observation is called the ___, and it is taken to motivate ___.
Show answer
Answer: D — poverty of the stimulus ... Universal Grammar
The gap between rich adult competence and limited input is the poverty of the stimulus, used to argue for an innate Universal Grammar. The cooperative principle and compositionality belong to pragmatics and semantics, and the Case Filter is a sub-module of syntax, not the acquisition argument.Which statements about Universal Grammar and competence are correct? Select all that apply.
Show answer
Answer: A — Universal Grammar is proposed as an innate basis shared by all human languages; B — Chomsky distinguishes tacit (implicit) knowledge of grammar from explicit knowledge about it; C — Core grammar is the UG-determined system, while the periphery covers idioms, borrowings and exceptions
Innate UG, the tacit/explicit distinction and the core/periphery split are all correct. The false option describes performance, not competence: competence is the speaker's internalised knowledge, while the real-time, error-prone record is performance.The principle of compositionality, commonly associated with Frege, states which of the following?
Show answer
Answer: A — The meaning of a complex expression is determined by the meanings of its parts and the way they are combined
Compositionality derives the meaning of a whole from the meanings of its parts and their mode of combination, which is exactly what lets us understand novel sentences. Context-dependence is pragmatics, one-meaning-per-word ignores polysemy, and the claim that unheard sentences cannot be interpreted contradicts the creativity that compositionality explains.The pair alive / dead and the pair hot / cold illustrate two kinds of antonymy. Which description is correct?
Show answer
Answer: B — alive/dead are complementary (binary) antonyms, while hot/cold are gradable antonyms
alive/dead are complementary: denying one entails the other, with no middle ground. hot/cold are gradable: there is a scale (warm, cool) between them. Converse antonyms like buy/sell describe the same relation from two sides, which neither pair does, so the other options misclassify them.The sentence 'John stopped smoking' is related to 'John used to smoke'. This relation is classed as a presupposition, and not merely as an entailment, because:
Show answer
Answer: C — it survives negation: 'John did not stop smoking' still conveys that he used to smoke
The hallmark of presupposition is that it survives negation: both 'John stopped smoking' and 'John did not stop smoking' presuppose that he used to smoke. An entailment would disappear under negation. Politeness and the quantity maxim are irrelevant, and a presupposition is not cancelled merely by asserting the sentence.Which statements about meaning relations are correct? Select all that apply.
Show answer
Answer: A — 'John killed the wasp' entails 'The wasp died'; B — Paraphrase is mutual entailment: two sentences with the same truth conditions; C — Two sentences contradict each other (are mutually inconsistent) when they cannot both be true at once
Entailment (kill entails die), paraphrase as mutual entailment, and contradiction as impossibility of joint truth are all correct. The false statement reverses the facts: it is a conversational implicature that is cancellable, whereas an entailment cannot be cancelled without contradiction.Asked 'Is your new colleague good at research?', a speaker replies 'Well, she is always on time for meetings.' The most likely conversational implicature, and the maxim being flouted, are which of the following?
Show answer
Answer: D — That the colleague is not especially good at research; the maxim of Relation (and Quantity) is flouted
By answering with something irrelevant to research and less informative than asked, the speaker flouts Relation (and Quantity), implicating that the colleague is not good at research. The reply does not assert she is outstanding, punctuality does not guarantee research quality, and an implicature is precisely an opinion conveyed indirectly rather than none at all.Which statements about pragmatics are correct? Select all that apply.
Show answer
Answer: A — Austin distinguished locutionary, illocutionary and perlocutionary acts; B — A conversational implicature is cancellable without contradiction, unlike an entailment; D — Grice's maxims fall under an overarching Cooperative Principle
Austin's three-way act distinction, the cancellability of implicature (versus the non-cancellability of entailment) and the Cooperative Principle governing the maxims are all correct. The false statement misdescribes deixis: deictic expressions shift their reference with the context of utterance, which is exactly what makes them deictic.A speaker says 'Some of the students passed the exam' and then adds 'in fact, all of them did', and the addition is not contradictory. What does this show about the usual 'not all' reading of 'some'?
Show answer
Answer: B — It is a scalar conversational implicature of the maxim of Quantity, so it can be cancelled without any contradiction
The literal content of 'some' is 'at least one'; the 'not all' meaning is a scalar implicature from the maxim of Quantity, and an implicature, unlike an entailment, can be cancelled without contradiction, which is exactly what the addition does. If 'not all' were entailed, cancelling it would be contradictory. A lexical ambiguity or a presupposition would not behave like this, since cancellation here leaves the sentence perfectly coherent.In English a question word is moved to the front (What did you read?), whereas in Hindi it typically stays where the corresponding argument would be (tumne kyā paṛhā?). In a principles-and-parameters view, this contrast is best described as which of the following?
Show answer
Answer: C — Variation in a parameter governing whether wh-phrases move overtly, within principles shared by both languages
Universal principles are shared, and languages differ in parameter settings; whether a wh-phrase moves overtly is a standard example of such a parameter. The verb assigns the same roles in both languages, Principle C concerns names and pronouns, not question words, and Hindi question words are fully rule-governed, so the claim that Hindi lacks Universal Grammar is wrong.
