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' means one lot of letters goes inside another (inserted letters are placed among others).
'treated' is an anagram indicator.
'sing'+'h'='singh'
'our'+'men'='ourmen'
'ourmen' anagrammed gives 'nurome'.
'singh' going inside 'nurome' is 'NURSING HOME'.
'in' is the link.
(Other definitions for nursing home that I've seen before include "Accommodation for the very frail" , "Residence for the elderly" .)
