Wages to enter back-to-front (6)
I believe the answer is:
income
'wages' is the definition.
(I've seen this in another clue)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for income that I've seen before include "Money gained from work or investment" , "Money coming in" , "Salary" , "Money gained over time" , "Wage" .)
