There are two types of bound morphemes: derivational and inflectional. Inflectional morphemes give a listener or reader information about how the word is used in a sentence. English does not have a lot of inflectional morphemes. An example of an inflectional morpheme in English is the "-ed" suffix for verbs. This morpheme at the end of a verb lets the speaker know that the action happened in the past. Another example is the "-s" suffix for nouns to show that there is more than one of the noun.
