The word "jealous" may be too strong, negative or inappropriate to use in certain situations. As an alternative, you could use a synonym to express the same idea more subtly. Some synonyms for "am jealous" include "envious", "covetous", "green with envy", "resentful" or "pining for". While these words have slightly different nuances and connotations, they all convey a feeling of wanting something someone else has, be it a trait, possession, or relationship. By using a synonym, you can communicate your feelings more tactfully and reduce the risk of offending or upsetting others.
