Last week, I described the nation state ideology of language, and its implications for language teaching. This week, I’m discussing folklinguistic theories of language, and their implications for language learning and teaching. Generally, “folklinguistic” theories, or the general population’s beliefs about language, are contrasted with “linguistic” theories developed via the scientific study of language, or linguists beliefs about language. Frequently, these are in conflict. There are, of course, multiple linguistic theories, indicating that linguists don’t necessarily agree on what language is either, and I’ll discuss some of those as they relate to learning and teaching languages in upcoming posts. However, for the moment I’ll focus on folk linguistic beliefs I come across in the field of language teaching that to the best of my knowledge are not supported by scientific theories of language.
