A sunny spot? (7)

I believe the answer is:

freckle

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

'spot?' is the definition.
(I know that freckle is a type of macula)

I can't explain the rest of the clue.

(Other definitions for freckle that I've seen before include "Lentigo" , "Brown mark on the skin" , "Brown spot on skin" , "Small skin spot" .)

I've seen this clue in The Globe and Mail.
