Source : Merriam -Webster
Etymology : The bale of baleful comes from Old English bealu ("evil"), and the bane of the similar-looking baneful comes from Old English bana ("slayer" or "murderer"). Baleful and baneful are alike in meaning as well as appearance, and they are sometimes used in quite similar contexts—but they usually differ in emphasis. Baleful typically describes what threatens or portends evil (e.g., "a baleful look," "baleful predictions"). Baneful applies typically to what causes evil or destruction (e.g., "a baneful secret," "the baneful bite of the serpent"). Both words are used to modify terms like influence, effect, and result, and in such uses there is little that distinguishes them.
