The disgrace of a big-headed clique? (4)
I believe the answer is:
blot
'the disgrace' is the definition.
(I've seen this before)
'big-headed clique?' is the wordplay.
'big-headed' becomes 'b' (this might be a standard abbreviation which I don't know about).
'clique?' becomes 'lot' (clique is a kind of lot).
'b'+'lot'='BLOT'
'of a' acts as a link.
Can you help me to learn more?
(Other definitions for blot that I've seen before include "bad mark" , "Stain on 1 across?" , "Cross out; inky mess" , "Dark mark or stain" , "Blemish made with ink" .)
