grout
GROWT
/ɡraʊt/
A fluid cementitious mixture used to fill narrow cavities, tile seams, or hollow core voids in masonry.
Engineered with high fluidity so it can be pumped or poured without leaving internal air pockets.
The story behind the word. Originates from Old English grut (coarse grain meal or sediment). The textured consistency of coarse oatmeal porridge was metaphorically applied to watery cement-and-sand slurry used to fill structural gaps.
