Feature of barley used to make bread (5)
I believe the answer is:
beard
'feature of barley' is the definition.
'beard' can be an answer for 'feature' (I have seen 'Facial feature' mean 'beard' so perhaps 'feature' could also mean 'beard'). I'm not certain of the 'of barley' bit.
'to make bread' is the wordplay.
'to make' indicates an anagram.
'bread' is an anagram of 'BEARD'.
'used' acts as a link.
Can you help me to learn more?
(Other definitions for beard that I've seen before include "Facial feature" , "SECOND PART OF 14" , "Facial growth" , "Facial hair" , "Oppose with effrontery" .)
