“天經地義”，漢語成語，出自《左傳·昭公二十五年》：“夫禮，天之經也，地之義也，民之行也（Rites represent the rules governing the movement of heaven and earth as well as the code of conduct for the people. ）?！?/p>

天經地義本意是指“天地的規(guī)則與秩序（the rules and orderliness of heaven and earth）”，后來被廣泛地用以描述各種事物的正當性及不容置疑的道理（the expression later came to mean anything that is proper, or any reasoning that is justified）?？梢苑g為“right and proper；perfectly justified”。

例句：

殺人償命，天經地義。
It is only right and proper that murder is punished by death.
