This bachelor thesis focuses on morphemes and word formations in the Swedish language. The main part of this thesis contains four parts. While the first part explains the difference between phonemes and morphemes, the second part focuses on division of morphemes. Furthermore, the third part provides a description and overview of the most important types of word formation in the Swedish language, and the fourth part is an analysis of morphemes and word formation in examples from the lists of newly created words published from 2016 to 2021 by swedish Institute of Language and Folklore (Institutet för språk och folkminnen). There are different types of morphems depending on their position in word, their funcion and meaning they give to a word. First basic division of morphemes is into free and bound morphemes, while sencond one is into root and grammatical morphemes. In addition to an overview of the basic divisions of morphemes in the Swedish language, this paper also describes the relationship between these divisions and explains allomorphs.
