Commonly used to describe strong, often negative feelings toward someone else's good fortune.
Remember that 'green with envy' is an idiom. Do not interpret it as someone literally turning green due to jealousy.
This idiom should only be used to describe feelings of jealousy, not other emotions like sadness or anger.
The phrase dates back to the 16th century, with 'green' symbolizing sickness or nausea (as in 'green about the gills') and 'envy' referring to jealousy. The combination reflects the physical and emotional turmoil of jealousy.
Primarily used in informal contexts. Avoid using it in formal writing unless quoting someone or using it deliberately for stylistic effect.
