Duty of bar discarding male's protective gear (4)
I believe the answer is:
task
'duty' is the definition.
(task is a kind of duty)
'bar discarding male's protective gear' is the wordplay.
I cannot really see how this works, but
'bar' could be 't' (T-bar is a part of a ski lift) and 't' is present in the answer.
The remaining letters 'ask' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'of' is the link.
Can you help me to learn more?
(Other definitions for task that I've seen before include "Assignment" , "Give mission" , "Errand, duty" , "Job of work" , "Piece of work to be done" .)
