semantic

adj. pertaining to semantics, of the study of the meaning and use of words and phrases

Semantics (Greek sēmantikos, giving signs, significant, symptomatic, from sēma , sign) refers to aspects of meaning, as expressed in language or other systems of signs. Semantics contrasts with syntax, which is the study of the structure of sign systems (focusing on the form, not meaning). Related to semantics is the field of pragmatics, which studies the practical use of signs by agents or communities of interpretation within particular circumstances and contexts. By the usual convention that calls a study or a theory by the name of its subject matter, semantics may also denote the theoretical study of meaning in systems of signs.
