A writer long out of fashion (5)
I believe the answer is:
quill
This clue could be a double definition.
'a writer' is the first definition.
(historical writing implement)
'long out of fashion' is the second definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
Can you help me to learn more?
(Other definitions for quill that I've seen before include "Porcupine spine" , "Feather for writing" , "Old writer" , "Hollow part of feather" , "Large feather" .)
