"Welcome" rug (3)
I believe the answer is:
mat
'welcome rug' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for mat that I've seen before include "Piece of material for wiping feet on" , "Rough piece of floor-covering" , "carpeting" , "Not glossy" , "Small protective floor-covering" .)
