Morphology

aleatory = alea + ory

The adjective is a learned borrowing from Latin (alea 'chance') with the suffix -ory; the root 'alea' is not a productive or familiar English base, so learners cannot reliably infer the meaning from its parts.

Etymology

The word aleatory comes from the Latin root alea, which means 'dice'. Think of throwing dice in a game: the result is left to 'chance', so aleatory describes something that depends on luck or is unpredictable.
