Duck late, perhaps (4)
I believe the answer is:
teal
'duck' is the definition.
(teal is a kind of duck)
'late perhaps' is the wordplay.
'perhaps' indicates an anagram.
'late' anagrammed gives 'TEAL'.
(Other definitions for teal that I've seen before include "Small, short-necked duck" , "Variety of small ducks" , "Small river duck" , "Duck - dark greenish-blue" , "Dark greenish-blue colour" .)
