prefix by Khizar Caliphate October 7, 2021
A word category that has no grammatical use or context outside of being appended to the beginning of a word to give it extra meaning. In some cases they are referred to as their own words, as when compounded together with specific words, they create no dictionary word, for example interuniversal, to mean "between universes".

Words that are prefixes are usually followed by a "-" when spoken about in definitions, or mentioned as the word itself and not by its definition, to denote that it is a prefix.
Common examples of Prefixes are: pre-, inter-, intra-, and post-.
