A depleted sprite turned in (5)
I believe the answer is:
among
'sprite turned in' is the definition.
I know nothing about this answer so I cannot judge whether this works.
'a depleted' is the wordplay.
'depleted' becomes 'mong' (I can't explain this - if you can you should give a lot more credence to this answer).
'a'+'mong'='AMONG'
Can you help me to learn more?
(Other definitions for among that I've seen before include "No mag (anag.)" , "In the number of" , "Amid" , "in a group" , "In an assembly of" .)
