過熱する
解説 Definition
機械やシステムが過度に熱くなる、または過度に熱くさせる。エンジンやコンピューターが適切に冷却されないと機能停止に至る可能性がある。
The third-person singular form of “overheat,” meaning that a machine, engine, or system becomes excessively hot, usually because it is working hard or is not being cooled properly.
覚え方のコツ Memory Tip
原形は overheat（over-「過度に」＋heat「熱する」）で、overheats は三人称単数現在形。heat が /t/ で終わるため、語尾の -s は /s/ と発音する。engine、CPU、system を主語にし、overheats under load や overheats without proper cooling という場面で覚える。
Start with the base verb “overheat”: “over-” means excessively, and “heat” means to make or become hot. “Overheats” is its third-person singular present form, used with subjects such as “the engine,” “the CPU,” or “the system.” Because “heat” ends in the voiceless sound /t/, the final “-s” is pronounced /s/. Remember it through typical warnings: an engine overheats in traffic, and a CPU overheats under heavy load or without proper cooling.
例文
The engine overheats when driving in heavy summer traffic.
夏の交通量が多い時間帯に運転するとエンジンが過熱します。
The CPU overheats if the cooling fan is not working properly.
冷却ファンが正常に機能していないとCPUが過熱します。
The system overheats under heavy computational load.
システムは重い演算負荷では過熱します。

overheats の語源・成り立ち Etymology
overheats は over-「過度に」+ heat「熱する」+ -s で、heat は古英語 hǣtan / hǣtu「熱」を語源に持ちます。つまり「熱をかけすぎる」がそのまま「過熱する」で、意味が形に表れた語です。関連語は hot, heater.
“Overheats” consists of the verb “overheat” plus the third-person singular ending “-s.” “Overheat” combines “over-,” meaning excessively or beyond a proper limit, with “heat.” “Heat” is historically related to Old English words including “hǣtu,” meaning heat, and “hǣtan,” meaning to make hot. The structure therefore directly expresses becoming or making something too hot.
