One of 100 in Scrabble (4)
I believe the answer is:
tile
'one of 100 in scrabble' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for tile that I've seen before include "Ceramic slab for roofs, walls, floors etc" , "Flat, thin slab to cover surface" , "Small slab of baked clay for covering walls, roofs etc" , "Oblong piece of glazed clay for bathroom wall" , "Thin slab of ceramic or slate" .)
