Prisoner as he got shot? (7)
I believe the answer is:
hostage
'prisoner' is the definition.
(hostage is a kind of prisoner)
'as he got shot?' is the wordplay.
'shot?' is an anagram indicator.
'as'+'he'+'got'='ashegot'
'ashegot' is an anagram of 'HOSTAGE'.
(Other definitions for hostage that I've seen before include "person captive to fortune" , "Person held by kidnapper for ransom" , "One caught" , "Prisoner held as surety" , "Person held by kidnappers" .)
