• prone

  Highlights vulnerability to something unwanted, such as illness or accidents; used as 'prone to' plus a noun or -ing form, never a bare infinitive; the most everyday of the four.

These four words mean likely to do something, but differ. Apt suggests a general tendency. Inclined shows personal willingness, based on current feelings. Given describes a deep, habitual, often critical trait. Prone highlights vulnerability to something unwanted, like illness.

这四个词都可以表示某人或某事“倾向于”或“很可能”做某事，但侧重点不同：apt 强调一般的、视情况而定的可能性；inclined 强调个人主观的意愿或倾向；given 强调根深蒂固、常带贬义的习惯性倾向；prone 强调容易遭受或做出负面的事情。这里不比较 apt 表示“恰当、贴切”的义项，不比较 inclined 表示“倾斜的”义项，不比较 given 作介词表示“考虑到”的用法，也不比较 prone 表示“俯卧的”义项。
