Biting the quick (5)
I believe the answer is:
nippy
I believe this is a double definition.
'biting' is the first definition.
(I've seen this in another clue)
'quick' is the second definition.
(I've seen this before)
'the' is the link.
(Other definitions for nippy that I've seen before include "Very cold - quick (informal)" , "Slightly cold?" , "brisk" , "Sharp" , "Fast - cold" .)
