オーバーホール
解説 Definition
overhauling は overhaul（徹底的に点検・修理する、全面的に見直す）の動名詞・現在分詞です。機械の分解整備だけでなく、制度や計画を大きく作り直す場合にも使われます。
The gerund or present participle of “overhaul,” referring to thoroughly examining and repairing machinery or extensively reorganizing a system, plan, or process. It implies substantial work affecting the whole object rather than a minor inspection or adjustment.
覚え方のコツ Memory Tip
原形 overhaul に -ing をそのまま加えた動名詞・現在分詞で、発音も overhaul の後に /ɪŋ/ が続きます。機械なら部品まで調べて直す「徹底整備」、制度なら仕組み全体を作り直す「全面見直し」です。overhauling an engine と overhauling a process を対で覚え、軽い点検の inspecting や部分修理の repairing より大規模だと押さえましょう。
Begin with the base verb overhaul and add -ing without changing its spelling: overhaul becomes overhauling. Imagine an engine being taken apart, inspected, repaired, and rebuilt; that is much more thorough than a quick check. Then transfer the same image to an application process, law, or organization whose parts are extensively redesigned. Common patterns include overhauling an engine, overhauling the heating system, and overhauling the application process. The word therefore signals comprehensive work, whether physical or administrative, rather than a small repair, routine maintenance task, or limited adjustment.
例文

overhauling の語源・成り立ち Etymology
overhauling は名詞 overhaul の -ing 形で、英語 over-「上から・越えて」+ haul「強く引く」から成ります。もとは航海用語で索具を逆に引いて点検することから「徹底点検・分解修理」へ広がり、オーバーホールが中まで引っぱり出して直す感じなのが見えます。関連語は haul, hale.
Overhauling is the -ing form of overhaul, a compound of over and haul. Haul is a Germanic word meaning to pull or drag. Overhaul developed in nautical use for pulling ropes or rigging through for examination or adjustment. From the idea of drawing components out and checking them thoroughly, it acquired the modern senses of extensively inspecting and repairing machinery and comprehensively revising systems or procedures.
