覚え方のコツ Memory Tip
overheating は over-「過度に」+ heat「熱する」+ -ing で、原形は overheat「過熱する・させる」。名詞では機器などが熱くなりすぎる現象「過熱」を指す。overheat の語末は t なので -ing をそのまま加え、発音は /ˌoʊvərˈhiːtɪŋ/。prevent overheating、signs of overheating で覚える。
Divide the word into over- + heat + -ing: over- means “too much,” heat supplies the idea of temperature, and -ing turns the process into a noun or participle. The base verb is overheat, and because it ends in t, simply add -ing: overheat → overheating, pronounced /ˌoʊvərˈhiːtɪŋ/. Picture a computer, engine, or battery becoming hotter than its safe operating range. Common phrases such as prevent overheating, signs of overheating, and damage caused by overheating make the noun use easy to recognize.

overheating の語源・成り立ち Etymology
overheating は over-「過度に」+ heat「熱する」+ -ing から成る語です。over と heat はともに古英語にさかのぼり、『必要以上に熱くなること』がそのまま『過熱』の意味に。関連語に overheat、reheat。
Overheating is transparently formed from overheat plus -ing. Overheat combines over-, here meaning “excessively” or “beyond a safe limit,” with the verb heat. Both over and heat have roots in Old English. The -ing form can name the process or condition as a noun, or describe an ongoing action as a participle. In technical contexts, the noun commonly denotes excessive, potentially damaging heat in machinery or electronic equipment.
