Definition
Noun: 1. The branch of semantics that studies the meanings and relations of words: Lexical semantics is a subfield of linguistics focused on analyzing the meaning of individual words (lexemes) and the systematic relationships between them within a language's vocabulary.
Usage
Lexical semantics is used as a singular, uncountable noun to refer to the academic discipline or theoretical framework. It is a compound noun where "lexical" modifies "semantics" to specify the type of semantics being discussed.
Examples
- Academic Context:

- Understanding polysemy is a central challenge in lexical semantics.
- General Context:
- The professor explained that lexical semantics is concerned with word meaning, not sentence structure.
Advanced Usage
- Theoretical Frameworks: Lexical semantics encompasses various theories for modeling word meaning, such as semantic feature analysis, prototype theory, and conceptual semantics.
- Different theories within lexical semantics offer competing explanations for how we categorize words like "bird" or "furniture".
- Computational Lexical Semantics: This is an applied subfield that develops models for word meaning to be used in natural language processing (NLP) and artificial intelligence.
- Word embeddings, like those from Word2Vec, are a key tool in modern computational lexical semantics.
