Understanding Morphology offers students an introduction to the study of work structure that starts at the very beginning. Assuming no knowledge of the field of morphology on the part of the reader, the book presents a broad range of morphological phenomena from a wide variety of languages. Starting with the core areas of infection and derivation, the book presents the interfaces between morphology and syntax and between morphology and syntax and morphology and phenology. The synchronic study of word structure is covered as are the phenomena of diachronic change such as analogy and grammaticalization. Theories presented clearly in accessible language with the main purpose of shedding light on the data, rather than as a goal in themselves. The author consistently draws on the best research available, thus utilizing and discussing both functionalist and generative theoretical approaches. Each chapter includes a summary, suggestions for further reading, and exercises. As such, this is the ideal book for both beginning students in linguistics, or anyone in a related discipline looking for a first introduction to morphology.
