1. A prefix is a group of letters (or an affix) that's added to the beginning of a word, and a suffix is an affix that's added to the end of a word. Prefixes modify the meaning of a word. They can make a word negative, show repetition, or indicate opinion. Some suffixes add to or change a word's meaning.
For example, the word “unhappy” consists of the prefix “un-” [which means “not”] combined with the root (or stem) word “happy”; the word “unhappy” means “not happy.” A suffix is a group of letters placed after the root of a word.
