Make someone do you a favour (6)

I believe the answer is:

oblige

I'm a little stuck... Click here to teach me more about this clue!

'make' is the definition.
(as in being obliged to do something)

I don't understand the remainder of the clue.

(Other definitions for oblige that I've seen before include "Compel (someone to do something)" , "serve" , "Compel, bind" , "Constrain" , "Hold in debt" .)
