The thing that gets me is "jealous" and "envious." People use them like they're interchangeable and they are not. Envy is wanting what someone else has. Jealousy is fearing you'll lose what you already have to someone else. Completely different postures — one's about lack, one's about threat.
This came up because of a menu, actually. Place near me — I won't say where I live exactly but there's a strip with three competing dumpling shops and one of them clearly ran everything through a translator that doesn't distinguish connotation from denotation at all. "Jealous Chicken" as a dish name. I stood there for a solid minute trying to work out what that could possibly mean before I decided it was probably meant to be something closer to "envy-inducing," like other chickens should be envious of this chicken.
Which is not the same as the chicken being jealous. The chicken has nothing to lose.
