Did You Know?

Disaster has its roots in the belief that the positions of stars influence the fate of humans, often in destructive ways; its original meaning in English was "an unfavorable aspect of a planet or star." The word comes to us through Middle French and the Old Italian word disastro, from the Latin prefix dis- and Latin astro, meaning "star." Another unfortunate word that comes to us from astrological beliefs is "ill-starred." Now generally used in the sense of "unlucky" or "having or destined to a hapless fate," "ill-starred" was originally used literally to describe someone born under or guided by an evil star. We also have star-crossed, meaning "not favored by the stars" or "ill-fated."
