Pen made from a feather (5)
I believe the answer is:
quill
'pen made from a feather' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for quill that I've seen before include "Large feather" , "Hollow part of feather" , "Old writer" , "Feather for writing" , "Porcupine spine" .)
