In simple terms
Semantics is the study of meaning in language. Broadly it covers the meaning of any linguistic expression. More narrowly it covers what words and sentences mean in themselves, set apart from what a speaker is doing with them on a particular occasion.
That narrow sense draws a useful line. Semantics asks what a sentence means. Pragmatics asks what the speaker meant by saying it here, to this listener, for this purpose.
How it works
Semantic analysis treats meaning as something to be studied systematically rather than guessed at. One standard move is to hold the situation constant and ask what survives. SIL Global’s glossary defines the narrow sense of semantics as the meaning of linguistic expressions considered apart from pragmatic factors such as features of the context, conventions of language use and the goals of the speaker.
A second move is compositionality, the idea that a sentence’s meaning is built out of the meanings of its parts and the way they are put together. The Stanford Encyclopedia of Philosophy records that early contemporary philosophy of language concentrated on that combining process and gave individual word meanings a marginal role, and that there is now widespread consensus that word meaning is crucial to understanding human language. That is a shift in research emphasis, not a settled finding about how meaning works.
Why it matters
Meaning is where disputes land. A contract clause, a safety label, a statute and a medical instruction all depend on what the words mean independently of who happens to be reading them, which is why semantics sits underneath legal drafting, translation, terminology standards and the systems that answer search queries.
Where you’ll see it
- Dictionary and glossary writing, where each sense has to be separated
- Legal drafting and the interpretation of contracts and statutes
- Translation, where a word’s senses rarely map one to one
- Search engines and language models, which rank text by meaning rather than spelling
Example
Can you pass the salt? is, semantically, a question about ability. Its pragmatic force is a request, which is why nobody answers only yes.
Often confused with
Pragmatics, which studies meaning in use, and syntax, which studies how sentences are structured rather than what they mean.
Key facts
- Semantics is, generally defined, the study of the meaning of linguistic expressions.1
- In its narrower definition, semantics studies meaning apart from pragmatic factors such as context, conventions of language use and the goals of the speaker.1
- Early contemporary philosophy of language focused on how words combine into meaningful sentences and treated individual word meanings as marginal.2
- There is now widespread consensus among scholars that the study of word meaning is crucial to understanding human language.2
