plummet是一個英語單詞，具有名詞和動詞兩種詞性，發音為英[ˈplʌmɪt]/美[ˈplʌmɪt]，屬託福考試核心辭彙。作名詞時指鉛錘（建築測量工具）或數值的驟降現象；作動詞既可表示物體垂直墜落，也用於描述價格、數量等指標的急劇下跌。
該詞在經濟領域常用於描述股價暴跌（如“Sales plummeted by 50%”）、債券價值縮水等場景，在自然科學中可指氣溫驟降（如“降至-40℃”）。其動詞搭配包括"plummet down"（強調方向）和"plummet to"（指向具體數值），變位形式為plummets（三單）、plummeted（過去式）及plummeting（現在分詞）。
詞源可追溯至拉丁語"plumbum"（鉛），經古法語"plommet"（小鉛球）演變而來，鉛錘的垂直特性引申出"驟降"的現代語義。在近義詞辨析中，與"plunge"含入水意象不同，強調垂直方向的快速跌落。
