disaster

Disaster carries the old image of an event caused by a bad star or an unlucky alignment in the sky.

Disaster came into English through French and Italian forms meaning ill-starred. Its older image connects misfortune with the stars, while modern English uses the word for a serious failure or catastrophe.

Italian disastro combines a negative prefix with astro, star. The formation belongs to an astrological worldview in which an unfavorable star could explain misfortune. French transmitted the word into English during the sixteenth century.
