This volume on language contact is a corpus-based descriptive and theoretical study of the Polish translations of English one- and multi-word polymorphemic expressions. The formation of loan translations is unique among strategies in lexical development as it involves three processes: borrowing, word-formation and semantic change. The study explores morphosyntactic, semantic and extralinguistic issues in the context of set expressions that are loan translated from a foreign language. It offers a typology of loan translations, loan identification criteria as well as a dictionary of over 500 loan translations from the English language.
