Queen having sunk a couple of pints reveals technique (3)
I believe the answer is:
art
'technique' is the definition.
(I've seen this in other clues)
'queen having sunk a couple of pints' is the wordplay.
I cannot quite see how this works, but
'queen' could be 'r' (abbreviation for regina, e.g. in ER ) and 'r' is located in the answer.
'a' is within the answer.
A single letter 't' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
'reveals' acts as a link.
Can you help me to learn more?
(Other definitions for art that I've seen before include "Trickery" , "For example, Blakey's creative" , "Works of beauty created by humans" , "Creative works; knack" , "Paintings etc." .)
