Types and peculiarities of languages

Differences and distinctions between spoken and written language are at the root of many issues and problems in literacy development. First, the transition from a predominantly spoken competence in a language to parallel competence in spoken and written language is a key educational process. Second, judgments of correctness in language are often too closely tied to judgments of correctness in the written form of the language. Third, linguistic descriptions of English as a language and of many other world languages have until very recently been based almost exclusively on written examples.
