Following is the definition of the word prefix

Answer 1

A prefix is a word part that is added to the beginning of a base word to create a new word with a different meaning. It precedes the base word and can modify, enhance, or negate its meaning. For example, the prefix "un-" added to the base word "happy" creates the new word "unhappy," which means not happy. Common prefixes include "pre-" (before), "re-" (again), "dis-" (not), and "bi-" (two).
