At work, he has to subdue his pride (4,5)
I believe the answer is:
lion tamer
'at work' is the definition.
I don't know anything about this answer so I cannot tell whether this works.
'he has to subdue his pride' is the wordplay.
I cannot really see how this works, but
'he' could be 'lion' and 'lion' is found in the answer.
'subdue' could be 'tame' (synonyms) and 'tame' is present in the answer.
A single letter 'r' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for lion tamer that I've seen before include "Who calms the beast" , "Circus act" , "Brave circus performer" , "like Daniel was" .)
