Rough and husky (6)
I believe the answer is:
'rough and husky' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for hoarse that I've seen before include "Having a frog" , "A horse with croaking voice" , "As if with a sore throat" , "(Of a voice) gruff or husky" , "Of voice, rough and dry" .)
