Morphemes are what make up words. Often, morphemes are thought of as words but that is not always true. Some single morphemes are words while other words have two or more morphemes within them. Morphemes are also thought of as syllables but this is incorrect. Many words have two or more syllables but only one morpheme. Banana, apple, papaya, and nanny are just a few examples. On the other hand, many words have two morphemes and only one syllable;
Examples include: cats, runs, and barked.
Definition of morpheme:
a combination of sounds that have a meaning. A morpheme does not necessarily have to be a word. Example: the word cats has two morphemes. Cat is a morpheme, and s is a morpheme. Every morpheme is either a base or an affix. An affix can be either a prefix or a suffix. Cat is the base morpheme, and s is a suffix.
