This document provides an introduction to word morphology and discusses its purposes and components. Morphology is the study of word structures and forms. There are two main purposes for studying morphology: creating new words and modifying existing words. Words have an internal structure and are composed of smaller units called morphemes, including roots, prefixes, and suffixes. Roots provide a word's basic meaning, while affixes like prefixes and suffixes can change a word's part of speech or meaning.
