Father grabbing whiskey and wife fruit (6)
I believe the answer is:
Here is my best explanation:
'fruit' is the definition.
(pawpaw is a kind of fruit)
'father grabbing whiskey and wife' is the wordplay.
'father' becomes 'papa' (papa is a kind of father**).
'grabbing' indicates putting letters inside.
'whiskey' becomes 'w' (alpha bravo charlie delta ...).
'and' means one lot of letters go next to another.
'wife' becomes 'w'.
'papa' going around 'w' is 'pawpa'.
(Other definitions for pawpaw that I've seen before include "Papaya", "Custard apple tree", "foul once", "Fruit" and "fruit".)
