Prefixes are morphemes that can be attached to the beginning of a word in order to change its structure and meaning. Some prefixes can be productively added to words to create new words, and some cannot and are exclusively used to create words on an approval basis through the LEP and Paul Frommer. Productive prefixes will be marked with pro. while unproductive prefixes will be un-marked. Prefixes that cause lenition will be marked with +​.
