Selçuk Üniversitesi Sosyal Bilimler Enstitüsü Dergisi, 6, 413-421.2667-4750https://hdl.handle.net/20.500.12395/47319When we say that someone knows a language, first of all, we mean that he has a knowledge of the rules which control the formation of sentences and which regulate the way in which units of language combine together. He can produce an infinite number of sentences using the knowledge of rules. However, while knowledge of grammatical rules will help him in creating sentences, it doesn't mean that they are appropriate for communication. Widdowson and Criper (Corder; 1975: 155) point out that " to know language as a formal system we need to know the rules which generate well formed sentences but to know language as a means of communication we need to know those conventions of use which control the selection of well formed sentences appropriate to a particular situation." To know a language, then means to know something about how language is used as a means of communication.eninfo:eu-repo/semantics/openAccessArticle6413421
