冷却
解説 Definition
cooling は、物や空気などの温度を下げることを表す名詞です。機械、建物、食品、体などが熱くなりすぎないようにする働きや過程を指します。
The process, action, or system of lowering the temperature of an object, substance, room, machine, or body. Cooling removes or disperses heat and helps prevent equipment, food, or people from becoming excessively hot.
覚え方のコツ Memory Tip
cool（冷やす、涼しくなる）に -ing をそのまま付けた語で、母音字が2つ続くため l は重ねない。名詞では温度を下げる過程や機能を指し、cooling system、air cooling、cooling process が典型。「冷たい状態」の coolness ではなく、熱を逃がして温度が下がる働きに注目する。
Cooling is formed by adding -ing directly to cool; the final l is not doubled. As a noun, it refers to the process or function of making something cooler, rather than simply describing a low temperature. Picture heat leaving a server room, engine, or bowl of soup. Common combinations include cooling system, air cooling, and cooling process. Compare it with coolness, which describes the quality or state of being cool: cooling emphasizes a change in temperature or a mechanism that produces that change.
例文

スープを数分冷ますと食べやすくなる。

cooling の語源・成り立ち Etymology
cooling は古英語 col「涼しい」に由来する cool に、動作や状態を表す接尾辞 -ing が付いた語です。語源どおり「熱を下げて涼しくすること」で、coolness や coolly と同じ核から意味が広がっています。
Cooling is formed from cool and the suffix -ing, which can name an action or process. Cool comes from Old English col, meaning moderately cold or not warm, and is related to other Germanic words with similar meanings. The verb developed the sense “to make or become less hot.” Adding -ing produces cooling, referring to that temperature-lowering action, process, or function, particularly in machinery, buildings, food handling, and the body.
