Be very nosy about closure of stone quarry (4)
I believe the answer is:
prey
'quarry' is the definition.
(I know that quarry can be written as prey)
'be very nosy about closure of stone' is the wordplay.
'be very nosy' becomes 'pry' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'about' indicates putting letters inside.
'closure of' says to take the final letters.
The last letter of 'stone' is 'e'.
'pry' going around 'e' is 'PREY'.
Can you help me to learn more?
(Other definitions for prey that I've seen before include "Predator's victim" , "Animal hunted and killed for food" , "Animal's quarry" , "Quarry, target" , "Animal sought as food" .)
