I believe the answer is:

homer

I'm a little stuck... Click here to teach me more about this clue!

'poet?' is the definition.
(Homer is an example)

I cannot understand how the remainder of the clue works.

(Other definitions for homer that I've seen before include "Blind man" , "addition to the score?" , "Epic poet - score at baseball - kind of pigeon" , "Great Greek who was known to nod" , "Weak official" .)

I've seen this clue in the Evening Standard.
