Sometimes people make up words by adding a prefix. These words are not in a dictionary. But if people use these words enough, sometimes they go into dictionaries. For example, we can make the word unsimple, which splits up into not simple. This is not a word in a dictionary.
Compare to suffix. Suffixes are letters put at the end of a word to change its meaning.
