口不對心 英文翻譯

what you say is not what u thinking

這句至少要改為 What you say is not what you THINK

One who acts differently as promised.
or
He/she didn't do as said.

「口不對心」最近似的英文單字是 duplicity. 請看 Webster 的釋義:
contradictory doubleness of thought, speech, or action; especially : the belying of one's true intentions by deceptive words or action
雖然 duplicity 並不是甚麼艱澀或過時的字, 但日常口語中很多人會把「口不對心」直接"描述"出來, 即 to say one thing and mean another:
為甚麼女性時常口不對心?
"Why do women always say on thing when they actually mean something else?"

上例應是: "Why do women always say one..."

口不對心即是講假話啦, 可以說
He says “Yes” but means “No”;
He gives verbal promise only;
He speaks false words;
He has another motive;
He has another way of looking at it;
He is not speaking from his heart.

按照你的句子情景選一個適用的吧!
