grout
目地材
解説 Definition
grout は、タイルや石材のすき間を埋める目地材という意味です。日本語でも建築や内装の分野で「グラウト」と言いますが、英語では日常的な修理や浴室の掃除の文脈でも使われます。
Grout is a fluid or paste-like building material used to fill and seal the narrow spaces between tiles, stones, or structural components. After it hardens, it helps stabilize the installation and keeps debris or moisture out of the joints.
覚え方のコツ Memory Tip
grout はタイル同士を接着する mortar そのものではなく、施工後の細いすき間を埋める「目地材」です。the grout between the tiles、fresh grout、remove old grout という組み合わせで、浴室の白い目地を補修・清掃する場面ごと覚えると用途を区別できます。
Picture the visible lines between bathroom tiles: the material in those narrow joints is grout. Learn it through the phrase the grout between the tiles, along with fresh grout and remove old grout. This separates it from mortar, which is commonly used beneath or between larger masonry units to bind them together. Grout starts as a workable mixture that can be pressed or poured into gaps and then hardens. The everyday contexts of cleaning stained grout and replacing cracked grout make the meaning especially easy to retain.
例文
The grout between the tiles is white.
タイルの間の目地材は白です。
We need fresh grout around the bathroom floor.
浴室の床まわりに新しい目地材が必要です。
The contractor removed the old grout before setting the new tiles.
業者は新しいタイルを張る前に、古い目地材を取り除きました。

grout の語源・成り立ち Etymology
grout は「目地に流し込むどろっとした材料」の意で、古英語 gruta「粗びき粉・おかゆ状のもの」に由来すると考えられます。さらにゲルマン祖語の「すりつぶす」系にさかのぼり、ざらついた詰め物の感覚から「目地材」の意味へ広がりました。関連語は grit, groats。
Grout is generally connected with Old English grūt, a word for coarse meal or a porridge-like substance, and with related Germanic words referring to coarse or ground material. Its history reflects the thick, gritty character of the mixture. The English noun later became established for a fluid or paste-like building material poured or pressed into joints, cracks, and spaces before hardening.
