POW in full (8,2,3)
I believe the answer is:
prisoner of war
'pow in full' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for prisoner of war that I've seen before include "Captured soldier" , "POW in full" , "Enemy captive" , "E.g. Stalag inmate" , "Captured member of enemy forces" .)
