Capable of being deceived, tricked, or misled; susceptible to deception.
From Latin decipere (to deceive) + -ible (capable of being). This adjective parallels 'deceptive' but means 'able to be deceived' rather than 'tending to deceive.'
This is one of those rare -ible words that means the opposite direction of what you'd expect—'deceptive' means something that deceives you, but 'deceptible' means you can be deceived by it!
