Identify the prefixes and or suffixes in the word. unbelievable

The prefix is "un" and the suffix is "able".

Your answer is prefix...and this is why

A prefix is an addition of something usually a word or letter at the beginning as a prefix or introduction..

A suffix is a morpheme added at the end of a word to form a derivative, e.g., -ation, -fy, -ing, -itis

If you take away the un you have believable, to change the meaning of the word they added un to the beginning of the word, that is a prefix.
