jealous

If you're jealous of someone, you want what they've got. This is one of the most basic human emotions, and it is not pretty. Don't be jealous of my good looks: you're cute too.

Being jealous is among the least attractive things you can be. The word jealous is actually derived from a Middle English word related to zealous, which means emotionally intense. It conveys a sense of emotional pain at someone else's good fortune. Jealousy is a close cousin of envy, but it can also mean "fiercely guarding" — as in "I am jealous of the little money I've managed to make, so I'm not likely to blow it on a cheap toy."
