Capable of being deceived or tricked; susceptible to deception.
From deceive (Latin decipere, to catch or ensnare) plus the suffix -able (capable of). It describes the quality of being vulnerable to dishonest tricks.
Interestingly, being deceivable isn't a weakness—it's actually a normal human trait, since we all make assumptions and take others at face value sometimes, which is why con artists will always have victims.
