Semantics Study Guide

📖 Core Concepts Semantics – study of linguistic meaning; how words obtain meaning and how complex meanings depend on their parts. Sense vs. Reference – sense: mental concepts/ideas attached to an expression; reference: the actual object the expression points to. Compositionality – meaning of a whole = function of meanings of its parts (strong = fully determined; weak = context/idioms can influence). Truth Conditions – the way the world must be for a statement to be true; central to truth‑conditional semantics. Semiotic Triangle – Symbol (word) ↔ Thought (concept) ↔ Referent (real‑world object); the link is mediated, not direct. Semantic Roles – Agent, Patient/Theme, Instrument, Experiencer, etc., describe participants in an event. Lexical Relations – synonymy, antonymy, hyponymy, meronymy; organize word meaning. Ambiguity vs. Polysemy – Ambiguity: unrelated meanings; Polysemy: related senses of the same word. Major Branches – Lexical, Phrasal, Formal, Cognitive, Computational, Pragmatic semantics. 📌 Must Remember Sense ≠ Reference (Frege). Strong compositionality ⇒ meaning fully determined by parts; weak allows context/idioms. Truth‑conditional meaning = set of possible worlds where the sentence is true. Core semantic roles: Agent (doer), Patient/Theme (affected), Instrument (means), Experiencer (feeler). Lexical hierarchy: synonym ≈ same meaning; antonym = opposite; hyponym ⊂ hypernym; meronym → part‑of. Causal theory of names – a naming event creates a causal chain linking the name to its referent (Kripke). Use Theory – meaning = way an expression is used in language games (Wittgenstein). Inferentialist semantics – meaning = set of valid inferences to/from an expression. Opacity vs. Transparency – substitution of co‑referential terms fails in opaque contexts (belief, modal). 🔄 Key Processes Compositional Meaning Construction Identify lexical items → retrieve senses. Determine syntactic structure (parse tree). Apply function‑application (e.g., λ‑calculus) to combine meanings per compositional rules. Deriving Truth Conditions Translate sentence to logical form. Map predicates to sets/relations, constants to objects. Specify world conditions that make the formula true. Causal Chain for Proper Names Naming event (baptism) → establishes initial referent link. Community transmission → each subsequent use inherits the link. Semantic Role Labeling (computational) Parse sentence → locate predicate. Identify arguments → assign Agent, Patient, etc., based on syntactic cues. Context‑mediated Meaning (Pragmatic Enrichment) Literal meaning → apply conversational maxims → generate implicatures → adjust truth conditions. 🔍 Key Comparisons Sense vs. Reference – Sense = how we think of the object; Reference = what the object actually is. Strong vs. Weak Compositionality – Strong: meaning fully fixed by parts; Weak: context/idioms may alter. Referential vs. Ideational Theories – Referential: meaning = external entity; Ideational: meaning = mental idea. Causal vs. Behaviourist Semantics – Causal: historical naming chain; Behaviourist: stimulus‑response patterns. Use Theory vs. Inferentialist Semantics – Use Theory: meaning = observable use; Inferentialist: meaning = inferential role. ⚠️ Common Misunderstandings “Semantics = Pragmatics.” – Semantics deals with literal meaning; pragmatics adds context‑dependent enrichment. All idioms violate compositionality. – Idioms are weak compositionality cases; many idioms still follow predictable patterns. Reference is always concrete. – Proper names can refer to non‑existent entities (e.g., “Pegasus”) → challenges referential theories. Synonyms are interchangeable in every context. – Subtle connotative differences or collocational constraints may block substitution. 🧠 Mental Models / Intuition Semiotic Triangle – Think of a map (symbol) that points to a city (referent) via a guide (thought). The map never touches the city directly. Compositionality as LEGO – Each piece (word) has its own shape (meaning); snapping them together yields a predictable structure (sentence meaning). Truth Conditions as “World‑Checklists.” – For a sentence to be true, imagine a checklist of world facts; if every item holds, the sentence is true. 🚩 Exceptions & Edge Cases Idiomatic expressions (“kick the bucket”) – meaning not reducible to parts. Opaque contexts (e.g., Lois believes that Clark Kent can fly) – substitution of co‑referential terms changes truth value. Non‑referential proper names (mythical entities) – challenge pure referential accounts. Polysemy vs. Homonymy – Polysemy retains related senses; homonymy involves unrelated meanings despite identical form. 📍 When to Use Which Truth‑Conditional analysis – when the exam asks for conditions under which a sentence is true or compares propositions. Causal theory of names – when discussing origin of proper‑name meaning or addressing reference without existing referent. Use Theory – for questions about language games, social conventions, or observable usage. Inferentialist semantics – when the focus is on logical consequences and inferential networks of expressions. Formal semantics (model‑theoretic) – when formalizing sentences into logical form or evaluating entailment. 👀 Patterns to Recognize “Agent‑Verb‑Patient” → typical predicate‑argument structure → map to semantic roles. “X is a Y” → hyponymy (Y is a supertype of X). Negation + Modal → often signals possible‑world quantification (necessity vs. possibility). “Believe/Think/Know” → likely opaque contexts; watch for substitution failures. “If… then…” → conditional truth‑condition pattern; evaluate antecedent & consequent worlds. 🗂️ Exam Traps Choosing “reference” for abstract terms – remember that abstract nouns may lack a concrete referent; the correct answer may be “sense”. Assuming all synonyms are interchangeable – exam may test subtle connotation or collocation differences. Confusing weak compositionality with non‑compositionality – idioms are weak compositional; they still obey some systematic constraints. Mixing up “semantic role” with “syntactic role.” – Agent is a semantic role; it may correspond to subject or not (e.g., passive constructions). Treating “meaning” as only mental (ideational) when the question references semiotic triangle – include the mediating thought component. --- Study this guide in short bursts; focus on the bolded terms and the bullet‑point patterns. Good luck!
