The document discusses the definitions and purposes of prefixes, roots, and suffixes in words. Prefixes are added to the beginning of words and can change a word's meaning, such as "pre-" meaning "before" or "un-" meaning "not." Roots are the main part of a word that prefixes and suffixes can be added to. Suffixes are added to the end of words and can indicate part of speech or change meaning, such as "-er" indicating a person or "-ness" indicating a state of being. Understanding prefixes, roots, and suffixes can help in determining the meanings of unknown words.
