adj.(形容词)

sufficient, adequate, ample, enough

这组词都有“足够的”意思。其区别在于：

1.enough为一般用语,有时可与adequate互换。enough常用来表示数量或程度,不宜用于表示性质、质量; 而adequate既可用于描述数量或程度,也可用于描述性质、质量。

2.adequate表示“仅够满足”“恰好满足”; enough和sufficient还可表示足够满足; 而ample表示充足而有余,即ample>sufficient>enough>adequate。

3.sufficient与enough同义,确切程度比 enough 大,前者多用于需要的满足,后者则多用于欲望的满足; 前者多用于书面语,后者多用于口语。

adequate，enough，sufficient

这些形容词均含“足够的，充足的”之意。

adequate指数量上足够，质量上适当。

enough最普通用词，口语、书面语可用，较侧重分量或数量的足够，多指希望的满足。

sufficient正式用词，侧重数目或数量或程度达到某一特定要求或需要。

• ☆ 14世纪晚期进入英语，直接源自古法语的sufficient；最初源自拉丁语的sufficiens。
