This document discusses morphology and defines key morphological terms. Morphology is the study of the internal structure of words and their formation. A morpheme is the smallest unit of meaning. There are two types of morphemes: bound morphemes, which cannot stand alone as words, and free morphemes, which can. Affixes like prefixes and suffixes are bound morphemes that can change the meaning or part of speech of words. Derivational morphemes form new words while inflectional morphemes indicate grammatical functions. Understanding morphology helps with reading, spelling, and vocabulary development.
