Floor or table protector (3)
I believe the answer is:
mat
I believe this clue is a double definition.
'floor' is the first definition.
(thesaurus)
'table protector' is the second definition.
(I've seen this in another clue)
(Other definitions for mat that I've seen before include "Foot-wiper on which welcome may be kept" , "Tangle" , "Dull, rug" , "Thick flat pad on the floor" , "Small protective floor-covering" .)
