About to drink gin? Rubbish! (8)
I believe the answer is:
claptrap
'rubbish' is the definition.
(thesaurus)
'about to drink gin?' is the wordplay.
I cannot really understand how this works, but
'about' could be 'c' (abbreviation for 'circa') and 'c' is located in the answer.
'drink' could be 'lap' (lapping is a kind of drinking) and 'lap' is located in the answer.
'gin?' could be 'trap' (I've seen this in other clues) and 'trap' is located in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for claptrap that I've seen before include "Meaningless nonsense" , "Cobblers" , "Utter rubbish" , "moonshine" , "Pretentious talk used to win applause" .)
