  1. Prefix

    A prefix is an affix which is placed before the stem of a word. Adding it to the beginning of one word changes it into another word. For example, when the prefix un- is added to the word happy, it creates the word unhappy. Particularly in the study of languages, a prefix is also called a preformative, because it alters the form of the words to which it is affixed. Prefixes, like other affixes, can be either inflectional, creating a new form of the word with the same basic meaning and same lexical category (but playing a different role in the sentence), or derivational, creating a new word with a new semantic meaning and sometimes also a different lexical category. Prefixes, like all other affixes, are usually bound morphemes.In English, there are no inflectional prefixes; English uses suffixes instead for that purpose. 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.


  1. prefix

    A prefix is a word part added at the beginning of a base word or root word to create a new word with a different meaning. It alters or enhances the meaning of the word. Examples include "unhappy" where "un-" is the prefix meaning "not", altering the meaning of the base word "happy."
