Carol’s husband among our men treated in hospice (7,4)
I believe the answer is:
nursing home
'hospice' is the definition.
(thesaurus)
'carol's husband among our men treated' is the wordplay.
'carol' becomes 'sing' (carol can mean to sing carols).
'husband' becomes 'h' (abbreviation).
'among' indicates putting letters inside (inserted letters are placed among others).
'treated' indicates an anagram.
'sing'+'h'='singh'
'our'+'men'='ourmen'
'ourmen' is an anagram of 'nurome'.
'singh' inserted within 'nurome' is 'NURSING HOME'.
'in' acts as a link.
(Other definitions for nursing home that I've seen before include "Accommodation for the very frail" , "Residence for the elderly" .)
