Regret giving agent ten orders (6)
I believe the answer is:
repent
'regret' is the definition.
(synonyms)
'giving agent ten orders' is the wordplay.
'giving' is a charade indicator (letters next to each other).
'agent' becomes 'rep' (short for representative).
'orders' is an anagram indicator.
'ten' with letters rearranged gives 'ent'.
'rep' put next to 'ent' is 'REPENT'.
(Other definitions for repent that I've seen before include "Feel regret/remorse" , "Be sorry for wrongdoing" , "Feel guilty" , "Feel remorse for" , "Turn away from sin" .)
