He is jealous She is jealous They are jealous You are jealous I am jealous We are jealous There is not a term (adjective) we use in English that comes to mind to describe a jealous person other than to say the above sentences.

I agree with GlennS and I also add some synonyms. :) 1) Envious: covetous, desirous, resentful, grudging, begrudging, green (with envy). 2) A Jealous lover: suspicious, distrustful, mistrustful, doubting, insecure, anxious, possessive, proprietorial, overprotective. 3) Protective: vigilant, watchful, heedful, mindful, careful, solicitous.

The only thing that means exactly "jealous" is "A jealous person.". A jealous person would be someone who is hostile towards you because they think you have an advantage, or something that they don't have. A person could also be "envious", that would mean that they want what you have, or the advantage that you have, though they aren't actively hostile because of it.
