This book tackles morphology from a cognitive viewpoint and links theory and practice. Its practical aim is to provide a comprehensive description of the two essential areas of vocabulary building: derivation and compounding. It develops skills in analyzing morphological expressions, familiarizing readers with the mechanisms used in forming complex words. It highlights the impact on form of the three theories of word meanings alongside coverage of Langacker's cognitive grammar. Category theory, domain theory and construal theory are introduced and described, with exercises and questions to develop practical skills. Hamawand brings insights from the semantics of cognitive linguistics into a field that lacks a book from this viewpoint. The book features a companion website with further exercises and questions, and will provide an innovative perspective for students on linguistics courses looking at grammar and morphology.
