This thesis comprises five translations with commentary. Excerpts from three books were translated from English into Croatian (The Establishment: And how they get away with it by Owen Jones, Making minds: What's wrong with education - and what should we do about it? by Paul Kelley, Reclaiming Conversation: The Power of Talk in a Digital Age by Sherry Turkle), and two from Croatian into English (Ekološki otisak: kako je razvoj zgazio održivost by Dražen Šimleša and Iran u prezentu by Ivan Đogić). The commentary focused on achieving equivalence in the target text. Sometimes, equivalents may be found in dictionaries or glossaries, but it is the translator’s task to assess the appropriateness of each in a given situation because equivalence arises in a particular situation and in a particular context. Therefore, in order to achieve equivalence in the target text, which ultimately leads to a faithful, accurate and idiomatic translation, various aspects need to be taken into account, e.g. the meaning of the original, the author’s style or tone, the author’s consistency and accuracy when using terms, the context and nature of the source text, possible equivalents, and connotations and effects of each solution. This method requires the translator to combine linguistic and extralinguistic knowledge and this is what leads to a successful and quality translation.
