Derivational Suffixes
When derivational suffixes are added to base words several things happen. First the grammatical function of the word usually changes. The verb deliver becomes the noun delivery, the adjective straight becomes the verb straighten. Sometimes there is a spelling change as when the final e in pure is dropped in purify and the y in colony changes to an i in colonize.
