Morphology

stochastic = stochast + ic

The combining form 'stochast-' is not a standalone English word, so learners cannot derive 'stochastic' ('random') from a familiar base plus '-ic'.

Etymology

Stochastic comes from the old Greek root stoch- (seen in stochastikos) meaning 'aim' or 'guess'. Think of it like taking a shot at a target when you are unsure — that idea of 'guessing' became the sense of 'random', so stochastic describes things that happen by 'chance' or without a clear pattern.
