A greedy person is someone who is always looking to amass more wealth or possessions than they need, often at the expense of others. Synonyms for greedy include avaricious, grasping, covetous, insatiable, insistent, acquisitive, rapacious, gluttonous, voracious, hoarding, and materialistic. Each of these words denotes excessive desire or craving for something, whether it is money, food, or other material objects. While there are different degrees of greed, all are marked by a lack of empathy or concern for others and a selfish focus on one's own desires. It is important to recognize and avoid such behavior in oneself and others to build healthy and harmonious relationships.
