覚え方のコツ Memory Tip
建築語の mortar は、セメント・砂・水などを練り、れんがや石の間に塗って固定する「モルタル」です。brick and mortar、spread mortar between the stones が典型表現。concrete は骨材を含み構造物自体を作る材料、grout は隙間を埋める流動性の高い材料なので、「部材同士を接着する層」と覚えると区別できます。
Think of mortar as the workable layer placed between separate building units. A mason spreads it between bricks or stones; it then hardens and holds them together. Learn the fixed phrase brick and mortar and the action spread mortar. Mortar is not identical to concrete: concrete commonly includes coarse aggregate and can form substantial structural elements, while mortar is generally used for bonding masonry or coating surfaces. Grout is usually more fluid and is designed to fill joints or spaces. The word also has a separate meaning for a weapon that fires shells, but this entry concerns only the construction material.

彼は石と石の間にモルタルを塗りました。

mortar の語源・成り立ち Etymology
mortar は古フランス語 mortier を経て、ラテン語 mortarium「混ぜる鉢・すり鉢」にさかのぼる。もとは材料を練る容器の名が、そこで作る塗り材そのものを指すようになった語。mortarboard も同系で、練って固めるイメージが共通する。
Mortar reached English through Old French mortier from Latin mortārium, a vessel used for pounding or mixing materials—the source of the word for a mortar paired with a pestle. The name of the mixing vessel was transferred to the paste prepared in such a container and then to the building material itself. This development preserves the practical image of ingredients being mixed and worked into a substance that later hardens between stones or bricks.
