Prefixes and suffixes are not words. They are groups of letters added to words. They change the meanings of words. We add prefixes to the beginning of a word to change its meaning. For example, un + happy becomes unhappy, meaning nothappy. Suffixes go at the end of words. They change a word’s meaning, and sometimes they change the word’s part of speech. For example, beauty + ful becomes beautiful, meaning full of beauty. Beauty is a noun, but beautiful is an adjective. In this posting I give you some of the most common prefixes and suffixes. In addition, I give you their meanings and some example words. The download at the end will give you additional practice using prefixes and suffixes.
