Semantics
Semantics is the branch of linguistics and philosophy concerned with the study of meaning in linguistic expressions.
Overview
The field divides primarily into lexical semantics, which studies individual word meanings and sense relations such as synonymy and hyponymy, and compositional or formal semantics, which investigates how the meanings of complex expressions are derived from their parts. Formal semantics employs logical systems and model-theoretic tools to analyze truth conditions and entailment relations. Cognitive semantics, by contrast, treats meaning as grounded in embodied conceptual structures, prototypes, and cognitive frames.
Why it matters
Semantic concepts inform natural language processing and knowledge representation systems in computer science. They also provide analytical tools for statutory interpretation in legal studies and for the investigation of semantic memory in cognitive science.

- LogichistoricalFormal semantics emerged from the convergence of mathematical logic and linguistics through Frege's distinction between sense and reference and Tarski's model-theoretic truth definitions.
- SemioticsconceptualSemantics focuses on the meaning of linguistic signs specifically, whereas semiotics addresses the broader study of all sign systems and their interpretation across human culture.
- Cognitive ScienceappliedCognitive semantics investigates how conceptual structures and mental representations underlie the meanings that speakers assign to words and utterances.
- Computational LinguisticsappliedDistributional and neural semantic models in natural-language processing technology derive word and sentence meanings from large text corpora, enabling machine translation and question answering.
- Philosophy of LanguageconceptualPhilosophy of language and semantics share foundational questions about reference, truth, and how language connects to the world, yet semantics focuses on systematic linguistic description while philosophy examines deeper metaphysical issues.
