覚え方のコツ Memory Tip
nose と dive という基本語が見えたら、「先端が下を向いたまま一気に落ちる」絵をまず頭に置くと定着しやすいです。そこから、飛行機だけでなく prices, sales, profits, ratings などが急落する場面にもそのまま広がります。slow decline のようなじわじわした下落ではなく、sudden drop や plummet に近い、短時間での急激な落ち込みを表す語。take a nosedive, go into a nosedive の形でもよく見ます。
Picture a plane with its `nose` pointing down as it `dives`. That image makes `nosedive` easy to remember. Then extend that picture to prices, sales, or ratings that fall very fast, not slowly.
