Did favours when compelled? (7)
I believe the answer is:
obliged
'compelled?' is the definition.
('oblige' can be a synonym of 'compel')
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for obliged that I've seen before include "Grateful - compelled" , "Morally or legally bound (to do something)" , "Compelled by duty" , "Did favour to, or coerced" , "Duty-bound" .)
