Abstract:
The improvement of EST translation requires the support of the appropriate theories. Though there are a lot of researches have been made, unfortunately, due to lack of a comprehensive theoretical framework to serve as a guideline, these studies are far from theoretical and systematic. Functionalist approach to translation is characterized by its target-orientation and it proposes that the communicative purpose of the translation should be used as the dominant principle in all translation activities. As such theories help develop a clear definition of the functions and purposes of EST texts,this paper briefly describes the main points of cognitive functional linguistics by following the road of the growth and makes an analysis of translation of EST for the perspective of the purpose and functions.
