- Semantics and Pragmatics :)

Semantics, particulary the area of lexical semantics, has been important to applied linguistics. Research in second-language acquisition and lexicography have both used lexical semantics as a resource for research on how words may be related, and on how they differ in various ways. The same concerns become important issues in vocabulary development as well, in both the teaching of language arts and the teaching of second languages.

Pregmatics, a historical development out of semantics, has had a much greater impact on applied linguistics, primarily because the issues raised and the theories developed directly inform discourse analysis.
