Prisoners recollected its name (7)
I believe the answer is:
inmates
'prisoners' is the definition.
(inmate is a kind of prisoner)
'recollected its name' is the wordplay.
'recollected' indicates anagramming the letters.
'its'+'name'='itsname'
'itsname' with letters rearranged gives 'INMATES'.
(Other definitions for inmates that I've seen before include "Inhabitants" , "Ties man (anag.)" , "Prisoners" .)
