Staff turn to get fruit (5)
I believe the answer is:
mango
'fruit' is the definition.
(type of fruit)
'staff turn' is the wordplay.
'staff' becomes 'man' (as in staffing or manning a particular place).
'turn' becomes 'go' (a person's move in a board game).
'man'+'go'='MANGO'
'to get' acts as a link.
(Other definitions for mango that I've seen before include "Asian fruit" , "product" , "No, Mag has the odd fruit" , "Ovoid edible fruit" , "Once exotic fruit" .)
