专业的fo经翻译“无常”是 impermanence -- 定义为“all of conditioned existence, without exception, is in a constant state of flux” 所有的存在,无一例外的,都是在处于常变的状态。有时候也用evanescence of life 或者 vanity of life,不过更强调huan灭和空xu的生活。
翻译如下反复无常根据语境caprice; play fast and loose; be unsteady; blow hot and cold; change like a weathercock; inconsistent 都可以例句你这人反复无常,真叫人难以捉摸。You are inconsistent and unpredictable.
