One banging about in the kitchen? (13)
I believe the answer is:
percussionist
'one banging about' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'the kitchen?' is the wordplay.
I cannot quite understand how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is located in the answer.
'kitchen?' could be 'percussion' (I've seen this before) and 'percussion' is found in the answer.
The remaining letters 'is' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'in' acts as a link.
Can you help me to learn more?
(Other definitions for percussionist that I've seen before include "Striking musician" , "Orchestral member" , "Banger" .)
