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 can't judge whether this works.
'he has to subdue his pride' is the wordplay.
I cannot really understand how this works, but
'he' could be 'lion' and 'lion' is found within 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 see.
This explanation may well be incorrect...
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" .)
