Got out of doing something (6)
I believe the answer is:
earned
'got' is the definition.
(earning is a kind of getting)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for earned that I've seen before include "Obtained through work" , "'Deserved, merited (6)'" , "Merited through work" , "well deserved" , "Got from paid employment merited" .)
