This is a succinct introduction to the burgeoning field of pragmatics, the study of language from the point of view of its users, of the choices they make, the constraints they encounter in using language in social interaction, and the effects their use of language has on other participants in an act of communication. Pragmatics reviews the work of Austin, Grice, Searle, Sacks and others and examines the implicit meaning of the irregularities of everyday conversation; and the social importance and the societal determination of even the least consciously proffered "act of language".
