Almost every word in every language is composed of one or more morphemes.
The allomorph is an abstract unit.
The existing form to which a derivational affix can be added is called a stem, which can be a bound root, a free morpheme, or a derived form itself.
Prefixes usually modify the part of speech of the original word, not the meaning of it.
