Put foot repeatedly in fruit tree (6)
I believe the answer is:
pawpaw
'fruit tree' is the definition.
(I know that pawpaw is a type of fruit tree)
'put foot repeatedly' is the wordplay.
'put foot' becomes 'paw' (I can't explain this - if you can you should believe this answer much more).
'repeatedly' says to double the letters.
'paw' doubled is 'PAWPAW'.
'in' is the link.
Can you help me to learn more?
(Other definitions for pawpaw that I've seen before include "Papaya" , "foul once" , "Fruit" , "Custard apple tree" .)
