Old man with chopped potato and fruit (6)
I believe the answer is:
papaya
'fruit' is the definition.
(I know that papaya is a type of fruit)
'old man with chopped potato' is the wordplay.
'old man' becomes 'papa' (synonyms).
'with' is a charade indicator (letters next to each other).
'chopped' means to remove the last letter (the final letter is chopped off).
'potato' becomes 'yam' (I have seen 'Sweet potato' mean 'yam' so perhaps 'potato' could also mean 'yam').
'yam' with its final letter taken off is 'ya'.
'papa'+'ya'='PAPAYA'
'and' acts as a link.
(Other definitions for papaya that I've seen before include "Tropical fruit tree used in medicine" , "Fruit with orange flesh" , "Custard apple" , "Tropical fruit with pink flesh and black seeds" , "Caribbean fruit" .)
