Translation studies scholars are also interested in studying the impact that translation or collections of translation have had in the sociocultural situation of the languages involved. They attempt to use existing theories of translation to predict what the process of translation is likely to involve for particular pairs of languages and types of text. This work has applications in translator training,The preparation of translation aids, such as dictionaries, grammars, term banks and in recent years, automatic translators, the establishment of translation policy.(which involves giving advice on the role of the translator in a given socio-cultural context,deciding on the econmic position of the translator, deciding which texts need to be translated, or deciding what role translation should play in the teaching of foreign languges)
