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."

Etymology

from early French desastre and early Italian disastro, both meaning "an unfavorable position of a star," from early Italian dis- (negative prefix) and astro "star," from Latin astrum "star"

Word Origin
People who have bad luck are sometimes said to be "star-crossed." This expression comes from the traditional belief that the positions of the stars and planets can have a direct influence on earthly events. The origins of the word disaster can be traced to this belief. Disaster comes from disastro, an Italian word formed by combining the negative prefix dis- and the noun astro, meaning "star." Disaster at first meant "an unfavorable position of a star or planet." In time it came to be applied to the kind of terrible misfortune which such a position was thought to cause.
