Kitchen flooring piece (4)
I believe the answer is:
tile
'kitchen flooring piece' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for tile that I've seen before include "Hat" , "Flat thin slab of clay, for example" , "Mah-jong piece" , "Flat piece of ceramic" , "Thin slab of fired clay" .)
