The definition of semantic
Semantic
is the study of meaning. It is a wide subject within the general study of
language. An understanding of semantics is essential to the study of language
acquisition (how language users acquire a sense of meaning, as speakers and
writers, listeners and readers) and of language change (how meanings alter over
time). It is important for understanding language in social contexts, as these
are likely to affect meaning, and for understanding varieties of English and
effects of style. It is thus one of the most fundamental concepts in
linguistics.
