After reflection, get a repository to store work (7)
I believe the answer is:
operate
'work' is the definition.
(synonyms)
'after reflection get a repository to store' is the wordplay.
'after reflection' is a reversal indicator.
'to store' says the answer is hidden in the clue (I've seen 'stores' mean this).
'etarepo' is hidden within 'get a repository'.
'etarepo' reversed gives 'OPERATE'.
(Other definitions for operate that I've seen before include "Perform surgery or run a machine" , "Manage, run" , "Control, run, a mcahine say" , "Cause to function" , "Conduct business in a theatre" .)
