IPA: /ˈdʒɛləsi/
KK: /ˈdʒɛləsi/
A feeling of wanting what someone else has, often leading to resentment or envy.
Her jealousy over her friend's success made her feel unhappy.
Jealousy is derived from the word "jealous" (from Old French *jalous*, meaning envious or suspicious) and the suffix "-y" (indicating a state or condition). The term "jealousy" refers to the state of being envious or suspicious, particularly in the context of relationships.
Think of feeling 'envious' or 'suspicious' — that's what jealousy means, and the '-y' shows it's a state of being.
