Etymology

disastrous = disast<bad star> + rous<adjective suffix>

  • disast (from Italian disastro, "ill-starred event," combining dis- <negative prefix> + astro <star>)
    Reflects the ancient belief that celestial events influenced fate.
  • rous (adjective-forming suffix, from Latin -osus, "full of")

Etymology Origin:
The word traces back to Italian disastro, literally "ill-starred," derived from the Latin dis- (expressing negation) and astrum (star). This reflects the astrological idea that calamities were caused by unfavorable planetary alignments. Over time, it shed its literal astrological sense and broadened to mean any catastrophic event.
