Family man with pretty secretary (7)
I believe the answer is:
grandpa
'family man' is the definition.
(type of male family member)
'with pretty secretary' is the wordplay.
'with' is a charade indicator (letters next to each other).
'pretty' becomes 'grand' (both can mean attractive or visually pleasing).
'secretary' becomes 'pa' (I've seen this in other clues).
'grand'+'pa' is 'GRANDPA'.
(Other definitions for grandpa that I've seen before include "senior citizen" , "Veteran" , "family member" , "Pop" , "much older relative?" .)
