A variety of bread to grind (6)
I believe the answer is:
abrade
'grind' is the definition.
(I've seen this in another clue)
'a variety of bread' is the wordplay.
'variety of' indicates anagramming the letters.
'bread' with letters rearranged gives 'brade'.
'a'+'brade'='ABRADE'
'to' acts as a link.
(Other definitions for abrade that I've seen before include "Shave" , "A beard (anag.)" , "Day breaks? > Start as before" , "Scrape away, erode" , "Wear away by rubbing, scrape" .)
