Like a quick bite? (5)
I believe the answer is:
nippy
'like' is the definition.
Both the answer and definition are adjectives. Perhaps they are linked in a way I don't understand?
'a quick bite?' is the wordplay.
I cannot quite see how this works, but
'bite?' could be 'nip' (nipping is a kind of biting) and 'nip' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for nippy that I've seen before include "A bit cold?" , "active" , "Fast - cold" , "Frosty - quick" , "Sharp" .)
