A low method of working for nothing (3)
I believe the answer is:
moo
'a low' is the definition.
(both can mean to make the noise of a cow)
'method of working for nothing' is the wordplay.
I cannot really understand how this works, but
'method' could be 'mo' (modus operandi, a particular method) and 'mo' is found within the answer.
'of' could be 'o' and 'o' is found within the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for moo that I've seen before include "Farmyard sound" , "unpopular woman" , "Irritating woman" , "Guernsey noise?" , "Cartoon sound of a cow" .)
