Dishonourable describes a person, an act, or a way of behaving that is not morally right — not just clumsy or unkind, but something that brings shame. If conduct is dishonourable, decent people would not respect it: breaking a promise for money, leaving friends in danger to save yourself, cheating in a way that stains your name.

Dishonourable describes不名譽這個詞形容的是 a person, an act, or a way of behaving一個人、一個行為，或一種做事的方式 that is not morally right在道德上是不對的— not just clumsy or unkind不只是笨拙或不親切， but something that brings shame而是會帶來羞恥的事。If conduct is dishonourable如果一種行為是不名譽的， decent people would not respect it正派的人不會尊敬它：breaking a promise for money為了錢毀約、leaving friends in danger to save yourself為了自保丟下有危險的朋友、cheating in a way that stains your name用讓自己名聲蒙污的方式作弊。

It is a heavy, rather formal word. You hear it in speeches, in history, in the army and the law, more than at the dinner table.

Though actually, people sometimes throw it around in a fight to sound grand, when they only mean “I don’t like what you did.” The tidy meaning is moral shame, not mere dislike.

Though actually不過其實， people sometimes throw it around in a fight有人吵架時會隨口甩出這個詞 to sound grand讓自己聽起來很有份量， when they only mean "I don't like what you did."但其實他們只是想說「我不喜歡你做的事」。The tidy meaning這個詞真正精準的意思 is moral shame, not mere dislike是道德上的羞恥，不只是不喜歡。
