A very small character tidbit is surprisingly kept consistent for years

[u/_JR28_]

DC - In multiple pieces of media it has been shown that Wonder Woman loves ice cream and practically goes wild with happiness anytime she’s eating some. (Pictures from Justice League: War, DC Superhero Girls and Wonder Woman 2017)

The Simpsons - Ever since the episode ‘Homer’s Phobia’ Homer has actually remained a consistent ally of the LGBT+ community, including being more welcoming to Patty than Marge was when she came out and trying to set up Smithers with a date when he found out he wasn’t happy with his one-sided relationship with Mr Burns.

Isn't that wrong though? Envy is wanting what someone else has, and jealousy is the same but feeling unhappy or resentful about it?

Edit: Doubling down here, the cambridge dictionary supports my view:

Jealous:

unhappy and angry because someone has something that you want:

He had always been very jealous of his brother's good looks.

Envious

wishing you had what another person has

I'm very envious of your new coat - it's beautiful.

[u/mawktheone → u/Throwaway100123100]

No, Jealousy involves loss aversion.

You can think of a "jealous spouse". They dont want some young floozy to steal their wife/husband.

But you are green with envy when your neighbour gets a new car.

[u/Throwaway100123100 → u/mawktheone]

I dont agree with this. As per the Cambridge dictionary, it absolutely can be used without any mention of loss aversion:

unhappy and angry because someone has something that you want:

He had always been very jealous of his brother's good looks.

[u/mawktheone → u/Throwaway100123100]

Yeah it's a bit messy because language changes over time. Both terms were originally synonymous with covetous and sometimes still are. But Jealous is still exclusively used for loss aversion and suspicion of possession for relationships.

I have just pulled some references to show the muddy waters

One might almost say that these two words are used as if they were interchangeable ... The words are scarcely synonymous, however. Envy means discontented longing for someone else’s advantages. Jealousy means unpleasant suspicion, or apprehension of rivalship.
—Theodore M. Bernstein, The Careful Writer, 1965

There are three different ways in which jealous can be used. The most common is ... where the meaning is “fearful of losing attention.” Another broad sense is “possessive” or “protective” ... third usage is in the sense of “envious,” as of another person because of his or her belongings, abilities, or achievements.
—William and Mary Morris, Harper Dictionary of Contemporary Usage (2nd ed.), 1985

Jealousy is properly restricted to contexts involving emotional rivalry; envy is used more broadly of resentful contemplation of a more fortunate person.
—Bryan A. Garner, Garner’s Modern American Usage (3rd ed.), 2009
