Qual é a diferença entre I'm jealous of you. e I envy you. ?Podes indicar apenas respostas exemplo.

Nowadays, there isn't one. IF you want to be technical, being jealous means you're afraid of losing something you already have; whereas being envious means you want something someone else has.

So say you have a partner and worry your partner likes someone else; you can say you're jealous of that someone else.
However, if you are that someone else and you want the other person's partner, then you're envious of that other person.

That said, most people use "jealous" to mean "envious" these days and I think some dictionaries have already changed the definitions to reflect common usage.
