Linguistic Society of America [SEP] Introduction
The Linguistic Society of America (LSA) is a learned society for the field of linguistics. Founded at the end of 1924 in New York City, the LSA works to promote the scientific study of language. The society publishes two scholarly journals, "Language" and the open access journal "Semantics and Pragmatics". Its annual meetings, held every winter, foster discussion amongst its members through the presentation of peer-reviewed research, as well as conducting official business of the society. Since 1928, the LSA has offered training to linguists through courses held at its biennial Linguistic Institutes held in the summer. The LSA and its 3,600 members work to raise awareness of linguistic issues with the public and contribute to policy debates on issues including bilingual education and the preservation of endangered languages.
