Unpleasant in a way that makes you want to keep your distance — and usually the distance is moral, not physical. If you call a person unsavoury, you mean there is something dishonest or shady about them: not proven criminal, but you would not want your daughter working for him. Newspapers love this word for exactly that reason. It lets you hint at wrongdoing without naming any, so it is safe to print. You also see it about places and situations — an unsavoury bar, an unsavoury business deal, unsavoury details of a divorce case — where the sense is "the sort of thing decent people do not want to be near or hear about." The original meaning is about taste: food with no good flavour, or a bad one. That sense still exists but is rare now; almost every time you meet the word, it is about character or reputation. It is a formal, written word. Nobody says it to your face in an argument; they say something ruder. Note the spelling: British writing uses unsavoury, American writing uses unsavory. Both are correct in their own place. One more thing — it is oddly one-sided. Savoury on its own now mostly means "salty rather than sweet" (savoury snacks), so unsavoury is not really the opposite of the savoury you meet on a menu. The two words have drifted apart.

不正派的、不三不四的、令人反感的（多指人品或場合可疑、上不了檯面）。講食物「不好吃、走味」的舊義現在少見
