This final paper deals with word-formation in English and Russian. It analyzes the differences, as well as the similarities, between various word-formation processes in the aforementioned languages and explains the semantic, syntactic and prosodic features of new words. Moreover, an overview of basic notions needed for the study will be introduced in order to offer a better understanding of morphemes and the classification of affixes in Russian and English. Furthermore, word-formation in English will be further explained by analyzing affixational (suffixation, prefixation, infixation and multiple affixation) and non-affixational (conversion, truncation, blending, abbreviation and compounding) processes while providing examples. Finally, word-formation in Russian will be introduced as well, and expounded by analyzing morphological (suffixation, prefixation, postfixation, multiple affixation, compounding and univerbation) and non-morphological (abbreviation, conversion and fusion) processes.
