Introduction:
Contrastive Linguistics, roughly defined as a subdiscipline of linguistics which is concerned with the comparison of two or more (subsystems of) languages, has long been associated primarily with language teaching. Apart from this applied aspect, however, it also has a strong theoretical purpose, contributing to our understanding of language typology and language universals.
The study of two languages in contrast, here called contrastive analysis, has been referred to by a variety of names, not all of which mean the same to all writers. One can find the following terms used: contrastive studies, contrastive language studies, contrastive linguistics, applied contrastive studies, contrastive description and others. contrastive analysis investigates the differences between pairs (or small sets) of languages against the background of similarities and with the purpose of providing input to applied disciplines such as foreign language teaching and translation studies. With its largely descriptive focus contrastive linguistics provides an interface between theory and application. It makes use of theoretical findings and models of language description but is driven by the objective of applicability. Contrastive studies mostly deal with the comparison of languages that are ‘socio-culturally linked’, i.e. languages whose speech communities overlap in some way, typically through (natural or instructed) bilingualism .
Much progress has been made in classifying the languages of the earth into genetic families, each having descent from a single precursor, and in tracing such developments through time. The result is called "comparative linguistics." Of even greater importance for the future technology of thought is what might be called "contrastive linguistics." This plots the outstanding differences among tongues - in grammar, logic, and general analysis of experience.A major influence on the development of the
