gullible

What does "gullible" mean?
To be "gullible" is to be easily deceived or tricked because you are too willing to believe what others tell you. Imagine someone who takes everything at face value, like a person who would genuinely try to buy a bridge if a stranger told them it was for sale; they lack the skepticism required to question if a story or claim is actually true. This word is often used to describe someone who is naive or overly trusting. While it can be used in a teasing way among friends, it carries a slightly critical tone, implying that the person needs to be a bit more street-smart or cautious before accepting information as fact.
