Gullible describes someone who trusts others too easily and is quick to believe things that may not be true. Gullible people can be easily tricked or fooled.
From “gull,” an old verb meaning “to cheat or trick,” possibly from a word for “throat” (as in swallowing things). The suffix “-ible” means “able to be,” so “gullible” is “able to be tricked.”
