Unpredictable → It is formed from "un-" (meaning not), "predict" (from Latin "praedicere", meaning to foretell), and "-able" (meaning capable of). The word "unpredictable" means not capable of being foreseen or foretold.
Think of 'not' ('un-') being able to 'foretell' ('predict') something — that's why unpredictable means you can't foresee it.
