One of five given this French fruit (6)
I believe the answer is:
quince
'fruit' is the definition.
(quince is a kind of fruit)
'one of five given this french' is the wordplay.
'one of five' becomes 'quin' (I've seen this before).
'given' is a charade indicator (letters next to each other).
'this french' becomes 'ce' (I've seen this in other clues).
'quin'+'ce'='QUINCE'
(Other definitions for quince that I've seen before include "Peter -- (A Midsummer Night's Dream)" , "Cinque (anag) - fruit" , "Peter --- (MND); fruit" , "Acid pear-shaped fruit used in preserves" , "Fruity" .)
