adjective
Pronunciation
GUL-ib-ul /ˈɡʌlɪb(ə)l/
Definition
Easily deceived or tricked; credulous; willing to believe things without sufficient evidence or critical thought.
Plain meaning
Gullible means easy to fool — someone who believes things too readily and can be persuaded without much effort, even by implausible claims.
Register
Informal to neutral. Gullible is an everyday word, slightly pejorative — to call someone gullible is a mild insult implying insufficient critical judgment. You wouldn't normally use it of yourself (few people consider themselves gullible) and would use it somewhat carefully of others.
