A prefix is a word element that is added to the beginning of a base word, root, or compound word to modify its meaning or create a new word. It is one of the two types of affixes, the other being suffixes. Prefixes generally do not change the word class or part of speech of the base word. Instead, they often denote negation, time, location, quantity, or various other grammatical and semantic meanings. Examples of prefixes include "re-" in words like "redo," "un-" in words like "undo," and "pre-" in words like "preview."
