Piece of ceramic flooring (4)

I believe the answer is:

tile

(Other definitions for tile that I've seen before include "Glazed piece of earthenware as for lining walls" , "Roofing slab" , "9 for the roof?" , "Flat thin slab of clay, for example" , "Hat" .)

I've seen this clue in the Newsday and the Universal.
