is the study of the meaning of words, phrases and sentences. In semantic analysis, there is always an attempt to focus on what the words conventionally mean, rather than on what an individual speaker (like George Carlin) might want them to mean on a particular occasion. This approach is concerned with objective or general meaning and avoids trying to account for subjective or local meaning. Doing semantics is attempting to spell out what it is we all know when we behave as if we share knowledge of the meaning of a word, a phrase, or a sentence in a language.
