What is the definition of "swindle"?

"Swindle" refers specifically to the act of deceiving someone for the purpose of obtaining money or property unlawfully. This term is often associated with fraudulent schemes where one party takes advantage of another's trust or lack of awareness. The essence of the word captures the notion of trickery and financial deceit, which aligns perfectly with the definition given in this context.

The other options do not convey the meaning of "swindle." For example, assisting someone in need implies a helpful and altruistic interaction, while investing wisely denotes sound and strategic financial decisions. Negotiating fairly also represents a scenario grounded in integrity and mutual benefit, which contrasts sharply with the deceptive nature of a swindle. Hence, the correct interpretation of "swindle" is indeed the act of cheating someone out of their money or property.
