Rapacious means aggressively greedy, taking or demanding far more than is fair or reasonable. A rapacious person grabs and seizes with an intense, almost violent desire for more, going far beyond ordinary wanting.

Picture a rapacious business owner who buys up all the competing stores in town just to control prices, or a rapacious landlord who charges unfair rents because tenants have nowhere else to go. The word suggests greed so extreme it harms others.

When you call someone rapacious, you're saying their greed involves seizing and consuming resources with ruthless hunger, often leaving nothing for anyone else. It's a harsh word reserved for truly excessive greed, not for someone who simply wants a second slice of pizza.
