Amid endless spree, briefly attempted to recover (8)
I believe the answer is:
retrieve
'recover' is the definition.
(synonyms)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for retrieve that I've seen before include "Get back or fetch" , "Get back (lost item)" , "Recover" , "Rescue" , "Go for and bring back" .)
