deceit (n.)
公元前1300年左右，“诡计，背叛，说谎”的意思来源于古法语 deceite，是 deceveir, decevoir, 的女性过去分词形式，源自拉丁语 decipere 的“陷阱，引诱，欺骗”，该词源自 de 的“来自”或蔑视（参见 de-），加上 capere 的“拿”，源自 PIE 基础词根 *kap- 的“抓住”。
从14世纪中叶起，其意为“欺骗的行为或实践”，也指“虚假的外表，错觉”。从14世纪晚期起，其意为“虚假或误导的质量”。
Deceit is a shorter and more energetic word for deceitfulness, indicating the quality; it is also, but more rarely, used to express the act or manner of deceiving. The reverse is true of deception, which is properly the act or course by which one deceives, and not properly the quality; it may express the state of being deceived. Fraud is an act or series of acts of deceit by which one attempts to benefit himself at the expense of others. It is generally a breaking of the law; the others are not. [Century Dictionary]
Deceit 是表示欺骗的品质的一种更短更有活力的词语; 它也常用于表示欺骗的行为或方式。相反， deception 右表示欺骗的行为或方式，而不是正确的品质; 它可以表示被欺骗的状态。Fraud 是一种企图通过欺骗他人从中获益的欺骗行为或一系列行为。通常情况下，它是违法的，而其他则不然。[世纪词典]
