What is the term for a person who is easily deceived or tricked?

The term for a person who is easily deceived or tricked is best described as gullible. This word specifically refers to someone who is overly trusting and lacks the critical judgment needed to detect deception. A gullible person often believes what they are told without skepticism, making them an easy target for scams or tricks.

Other terms, while related, don't quite capture the same nuance. For example, "naive" refers more broadly to someone who lacks experience or sophistication, which can lead them to be easily misled. "Dupe" can refer to either a person who is deceived or an act of deceiving someone, but it does not inherently describe a characteristic of the person themselves. "Fool" is a more general term that can imply a lack of wisdom or common sense but does not specifically address being easily deceived.

Thus, the term that most accurately describes a person who is easily deceived is gullible, as it emphasizes their propensity to believe what others say without question.
