Chap with energy finds fruit (5)
I believe the answer is:
mango
'fruit' is the definition.
(I know this)
'chap with energy' is the wordplay.
'chap' becomes 'man' (chap can mean a man).
'with' is a charade indicator (letters next to each other).
'energy' becomes 'go' (I've seen this in other clues).
'man'+'go'='MANGO'
'finds' acts as a link.
(Other definitions for mango that I've seen before include "Once exotic fruit" , "fruit tree" , "Fleshy tropical fruit" , "Fruit, often in chutney" , "Type of fruit" .)
