Ring and order fruit (6)
I believe the answer is:
orange
'fruit' is the definition.
(orange is a kind of fruit)
'ring and order' is the wordplay.
'ring' becomes 'o'.
'and' is a charade indicator (letters next to each other).
'order' becomes 'range' ('range' can be a synonym of 'order'**).
'o'+'range'='ORANGE'
(Other definitions for orange that I've seen before include "Dutch royal house" , "African flower" , "An ogre (anag.)" , "Colour between red and yellow" , "Stocking-filler fruit" .)
