Husband and child after return fare (4)
I believe the answer is:
nosh
'fare' is the definition.
(nosh is a kind of food)
'husband and child after return' is the wordplay.
'husband' becomes 'h'.
'and' says to put letters next to each other.
'child' becomes 'son' (male child).
'after return' is a reversal indicator.
'son' backwards is 'nos'.
'h' put after 'nos' is 'NOSH'.
(Other definitions for nosh that I've seen before include "Food (Yiddish)" , "Eat (sl.)" , "A slang meal" , "Food - eat greedily" , "Eat (slang) -- food (slang)" .)
