The course presents Translation Theory as it is understood in the academic discipline of Translation Studies. It opens with several ‘definitions’ of translation (Jackobson, Nida, Toury), and certain translation topics: Interlingual, intralingual and inter-semiotic translations; the notion of translatability; parallel texts; the notion of equivalence; adequacy vs. acceptability; translation procedures; translation of metaphors; machine translation, etc. It then moves to present central theories in TS: the Polysystem theory and Descriptive Paradigm, norms of translation and “translationese”; Skopos Theory; translation and the notion of transfer; etc.
