Pragmatics deals very broadly with the study of language in the social contexts in which it is used. It developed outside of linguistics in ordinary language philosophy, in particular under the influence of philosophers such as Ludwig Wittgenstein, John Austin, John Searle and Herbert P. Grice. The Anglo-American tradition, also termed 'the component view' or 'the pigeon-hole view', was particularly influenced by Geoffery Leech's textbook, Principles of Pragmatics, a renowned publication which determined the basis of the early discipline. Continental European tradition does not view pragmatics as one component of linguistic analysis, and is not concerned with marking boundaries with other components of language. Rather, it sees pragmatics as dealing with social meaning and representing a superordinate perspective on linguistic communication in general. The perspective view sees pragmatics as not only limited to linguistic research, but also as practised across neighbouring fields such as sociology or psychology.
