abstruse

义 abundant[ 'b nd nt]adj.大量的，丰富的，充足的

源 ab-加强+-und溢出；波动 +-ant……的→(多得)溢出来。表示“丰富的”、“充裕的”或“大量的”，常用来描述数量或供应充足的事物。

巧记

a (一) bund(磅的) ant蚂蚁，谐音“一磅的蚂蚁”，指大量的，充足的

例

abundant in富于；富有

abundant rainfall过量降雨

Oxygen is abundant in Earth's atmosphere.

地球上大气中氧含量丰富

There is abundant evidence to support his claim.

有充足的证据支持他的主张

辨lavish abundant affluent

三个词都有“丰富”之义。三者的词根分别是lav-冲洗, und-溢出。 flu-流动。“冲洗”比“溢出”，“流动”激烈，所以lavish,abundant,affluent丰富的程度依次减弱。 lavish非常浪费的，过分丰富的; affluent富裕的，富足的; abundant大量的，丰富的。另一个词ample(词根ampl-大)表示“大量的，充裕的”，谈不上丰富的。
