Aim, objective (4)
I believe the answer is:
goal
I believe this is a double definition.
'aim' is the first definition.
(I know that aim can be written as goal)
'objective' is the second definition.
(goal can mean an objective or purpose)
(Other definitions for goal that I've seen before include "Objective or score" , "Aim or purpose" , "Aim and objective" , "Target or ambition" , "Footballer's target" .)
