Prefixes : A Huge List of Prefix with Meaning and Examples

Sharing is caring!

Prefixes in English! Prefixes are letters which we add to the beginning of a word to make a new word with a different meaning. Unlike suffixes, prefixes can, for example, create a new word opposite in meaning to the word the prefix is attached to. The list below shows common prefixes in English that you should know.
