Semantics is the scientific and philosophical study of meaning in language. It examines how words and grammatical structures convey significance, distinguishing linguistic meaning from other forms like natural or intentional meaning.12

Studying Word Meaning

Research into word meaning has evolved from historical, or diachronic, studies—which track how meanings change over time due to shifts in usage or the objects they denote—to synchronic analysis. Modern approaches often utilize a lexicon, which acts as a dictionary that associates each word with specific syntactic and semantic features. For instance, a word might be categorized by features such as [+Animate] or [+Human], which dictate how it can be used within a sentence.34

Grammatical Structures and Meaning

In frameworks like transformational-generative grammar, semantics is integrated as a core component. Meaning is derived from the deep structure of sentences through specific rules of semantic interpretation. This approach treats grammar as an integrated system that relates the structure of a sentence to its meaning, ensuring that words are combined in ways that are semantically coherent rather than anomalous.42
