Morphemes just for fun
The science of linguistics breaks down language into its smallest units of grammar: the morpheme.
It's not the same as a syllable and can be either a phoneme (sound only) or a grapheme (the smallest unit of written language).
Think of prefixes and suffixes, both of which can be affixes if used with a base that can't stand alone. Thus the word unreliable has 3 morphemes: un, rely and able.
