Wall tapestry (5)
I believe the answer is:
arras
'wall tapestry' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for arras that I've seen before include "Polonius met his end behind one" , "Work of art" , "Tapestry; French town" , "Tapestry; WW One battle" , "Wall hanging of heavy woven fabric" .)
