hoarse

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

'a husky' is the definition.
(I've seen this before)

I don't understand how the rest of the clue works.

(Other definitions for hoarse that I've seen before include "Husky (from cold)" , "in need of throat spray?" , "(Of voice) rough, harsh" , "With strained voice" , "A horse with croaking voice" .)

I've seen this clue in The Times.
