Father — husband (3,3)
I believe the answer is:
old man
This clue is a double definition.
'father' is the first definition.
(I know that old man is a type of father)
'husband' is the second definition.
(thesaurus)
(Other definitions for old man that I've seen before include "Husband (inf)" , "Senior citizen" , "Husband - father - boss" , "Boyfriend" , "Elderly chap" .)
