What part of speech is jealous?

"Jealous" can be a few different parts of speech, depending on how it's used in a sentence:

* Adjective: Describing a noun, meaning feeling or showing envy or resentment.

* Example: "She was jealous of her friend's new car."

* Noun: The state or feeling of being envious or resentful.

* Example: "He was consumed by jealousy."

* Verb: To feel or show envy or resentment. This is less common.

* Example: "He jealoused his brother's success." (This usage is somewhat archaic and not very frequent in modern English.)

So, without context, you can't definitively say which part of speech it is.
