It's at the back of the house in many North American dialects. Linguistics is the systematic study of language in general. It investigates the structure and function of language, the way in which languages differ, and those properties which all languages share. As a result, it provides the tools for exploring any particular language, as well as for trying to explain numerous aspects of language use. Further, by comparing and contrasting individual languages, linguists have been able to make important discoveries which contribute to our understanding of the overall nature of the human mind.
Linguists investigate both spoken and written language.
They examine data from the twentieth century as well as from earlier historical periods. All varieties of all languages are of interest to linguists since all follow certain tendencies and all exhibit characteristic patterns. One can examine linguistic patterns on several different levels. Each language has its particular set of sounds, which are organised and employed in characteristic ways. Discourse Patterns Texts and conversations are structured bits of language which use all of the above for particular communicative purposes.
