It's returned in payments for jobs (6)
I believe the answer is:
duties
'jobs' is the definition.
The answer and definition can be both acts as well as being plural nouns.
Perhaps you can see an association between them that I don't see?
'it's returned in payments' is the wordplay.
'returned' says the letters should be written in reverse.
'in' means one lot of letters goes inside another.
'payments' becomes 'dues' (dues are a fee or charge).
'it' in reverse letter order is 'ti'.
'ti' placed within 'dues' is 'DUTIES'.
'for' is the link.
Can you help me to learn more?
(Other definitions for duties that I've seen before include "levies" , "Tasks; obligations" , "Obligations and responsiblities" , "Moral or legal obligations" , "Suited to responsibilities" .)
