A meaty piece of church music (4)
I believe the answer is:
chop
'music' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'a meaty piece of church' is the wordplay.
I cannot really understand how this works, but
'piece' could be 'p' (abbreviation for Pawn) and 'p' is found within the answer.
'of' could be 'o' and 'o' is located in the answer.
'church' could be 'ch' (common abbreviation) and 'ch' is present in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for chop that I've seen before include "Cut; slice of meat" , "Thick slice of meat including rib" , "Karate blow" , "mutton slice" , "Abolish, cut of meat" .)
