"Jealous" = fear of losing something you already have; "envious" = wanting something someone else has.
Adjective: resentment or fear produced by believing something you value (a partner, a position, attention) could be taken away or shared. There is always something you already have or feel is yours.
She felt jealous when her partner spent more time with colleagues than with her.
He became jealous of the attention his new baby sister was getting from their parents.
Ancient gods were often portrayed as jealous of human achievements that challenged divine authority.
Adjective: desire to have something someone else has that you do not — their success, their possessions, their talent. Does not imply currently owning anything; it is simply wanting what the other person has. Related to "envy".
She was envious of her colleague's promotion — she had worked just as hard but been passed over.
He was envious of his neighbor's new car and started saving up to buy a similar one.
I am truly envious of people who can sleep anywhere, on planes, in waiting rooms, anywhere.
Common mistake
In everyday colloquial usage, "jealous" is used for BOTH meanings (both jealousy and envy). Saying "I am so jealous of your vacation!" is colloquially acceptable, though technically it should be "envious" (you want their vacation, not fear losing your own). In formal or academic writing, maintaining the distinction shows vocabulary precision.
Trick to remember it
Key question: in this feeling, do you have something you could lose? If YES, it is JEALOUS. If NO, you want something someone else has, it is ENVIOUS. Memory trick: JEALOUS comes from "zeal" (fervor, guarding something with zeal). ENVIOUS comes from "envy" — you want what the ENVied person has.
Quick rule
Jealous = jealousy (you have something and fear losing it). Envious = envy (they have something you want).
Did you know?
The seven deadly sins clearly distinguished between "envy" (wanting what belongs to another) and wrath mixed with pride (which included jealousy). The words "jealous" and "zealous" (fervent) come from the same Greek root: "zelos" (fervor, ardor). In Biblical Hebrew, the same root is used to describe a "jealous God" — a god who guards with fervor the devotion of his believers.
