Cloth from flax (5)
I believe the answer is:
linen
'cloth from flax' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for linen that I've seen before include "Fine cloth for Lenin" , "Lenin (anag) -- fabric" , "Sheets, tablecloth etc." , "Fabric from the fibres of the flax plant" , "E.g. bedclothes" .)
