Bristle on a woven pelt (3)
I believe the answer is:
awn
'bristle' is the definition.
(botanical term)
'on a woven pelt' is the wordplay.
'on' is a charade indicator (letters next to each other).
'woven pelt' becomes 'wn' (I am not sure about this - if you are sure you should believe this answer much more).
'a'+'wn' is 'AWN'.
Can you help me to learn more?
(Other definitions for awn that I've seen before include "Bristly growth" , "Bristle-like appendage on grass" , "Bristle on cereal spike" , "bit of cereal" , "Bristle growing on barley" .)
