Adding a prefix to the beginning of an English word changes it to a different word. For example, when the prefix un-is added to the word happy, it creates the word unhappy. The word prefix is itself made up of the stem fix (meaning "attach", in this case), and the prefix pre-(meaning "before"), both of which are derived from Latin roots.
Unlike derivational suffixes, English derivational prefixes typically do not change the lexical category of the base (and are so called class-maintaining prefixes). Thus, the word do, consisting of a single morpheme, is a verb, as is the word redo, which consists of the prefix re-and the base root do.
