Salary or wage (3)
I believe the answer is:
pay
I believe this clue is a double definition.
'salary' is the first definition.
(I know that salary can be written as pay)
'wage' is the second definition.
(I know that wage can be written as pay)
(Other definitions for pay that I've seen before include "Reward for work" , "Profit" , "Screw" , "Hand over money for" , "Salary, wages" .)
