Complete the following sentence. in the word excitedly, -ly is a a: prefix. b: preposition. c: suffix. d: root.

It's not D because a root is something like "sub" in "subway" which means "under, below" or "ped" in "pedestrian" which means "foot." "-ly" has no particular meaning.

B, or a preposition, I believe, renames the subject. "-ly" does not rename any subject in particular, so that is also false.

A is not correct either simply because a prefix is a morpheme that goes at the beginning of a word. "-ly" is supposed to go at the end of a word.

So the correct answer is C, or suffix :)
