覚え方のコツ Memory Tip
plunging は原形 plunge に -ing を付けた現在分詞・動名詞です。語末の e を落として plunge → plunging となり、発音は /ˈplʌndʒɪŋ/。価格や売上、市場などを主語にした「prices are plunging」「keep plunging」を、単なる下降より急で大幅な落ち込みとして覚えましょう。
Start with the base verb plunge, meaning to fall suddenly and steeply. To form plunging, drop the final silent e before adding -ing: plunge becomes plunging, pronounced /ˈplʌndʒɪŋ/. Picture a graph dropping sharply rather than drifting downward. Common patterns are “prices are plunging,” “sales kept plunging,” and “a plunging market.” This image also helps distinguish plunge from decline or decrease, which can describe slower or smaller changes. Plunging emphasizes both speed and a substantial downward movement.

plunging の語源・成り立ち Etymology
ラテン語「plumbum（鉛製の錘）」を語源とし、接尾辞「-ing」が結合しています。水深測定で重りを水面へ一気に落とす動作が語源で、その鋭く沈むイメージが「急落する」の意味へ発展しました。同語根に「plumber（配管工）」が挙げられます。
Plunging is formed from plunge by dropping the final e and adding the participial suffix -ing. Plunge entered English through French and has been associated with the action of thrusting or sinking something forcefully, including lowering a weighted object into water. Its history is often connected with Latin plumbum, “lead,” because lead weights were used in sounding depths. The physical image of rapid downward movement later extended naturally to prices, temperatures, sales, and markets.
