Hence, more tailor-made language design can be adopted; examples include awareness raising teaching method and hierarchical learning teaching curriculum. Second language learning: Awareness raising is the major contribution of CA in second language learning. This includes CA's abilities to explain observed errors and to outline the differences ...
The aim of the comparative method is to highlight and interpret systematic phonological and semantic correspondences between two or more attested languages.If those correspondences cannot be rationally explained as the result of linguistic universals or language contact (borrowings, areal influence, etc.), and if they are sufficiently numerous, regular, and systematic that they cannot be ...
