This document discusses English morphology and how words are formed. It defines morphology as the study of words, and defines different types of morphemes - free morphemes which can stand alone as words, and bound morphemes which must be attached to free morphemes. It describes the different types of bound morphemes including inflectional affixes which do not change word meaning and derivational affixes which can change word class. The document also discusses the different parts of speech and how new words enter the language through processes like compounding, clipping, blending and borrowing. It provides an example analysis of classifying words in a passage.
