Succulent fruit piece, half gone (5)
I believe the answer is:
mango
'succulent fruit' is the definition.
'piece half gone' is the wordplay.
'piece' becomes 'man' ('man' can be a synonym of 'piece'**).
'half' means to take half the letters.
'gone' cut in half is 'go'.
'man'+'go'='MANGO'
(Other definitions for mango that I've seen before include "fruit tree" , "fruit-tree" , "Type of fruit" , "No, Mag has the odd fruit" , "Once exotic fruit" .)
