About to polish one’s rude answer (6)
I believe the answer is:
rebuff
'one's rude answer' is the definition.
I can't tell whether this defines the answer.
'about to polish' is the wordplay.
'about' becomes 're' (regarding).
'to polish' becomes 'buff' (buffing is a kind of polishing).
're'+'buff'='REBUFF'
Can you help me to learn more?
(Other definitions for rebuff that I've seen before include "Ungracious rejection of a friendly approach" , "Reject abruptly" , "'Slight, snub (6)'" , "Cold-shoulder" , "Snub or contemptuous refusal" .)
