Man and daughter getting on (3)
I believe the answer is:
don
'man' is the definition.
(Don is an example)
'daughter getting on' is the wordplay.
'daughter' becomes 'd' (genealogical abbreviation).
'getting' means one lot of letters go next to another.
'd'+'on'='DON'
'and' is the link.
(Other definitions for don that I've seen before include "Mafia supremo" , "Put on or assume" , "Spaniard in a University?" , "Nod off like Mafia chief" , "- - Giovanni, 26" .)
