Usage Note

Avoid using sense 2 in formal reports or serious contexts, where disastrous or very serious would be more appropriate.

Synonym discussion

Sense: adjective/1

All four words describe events that cause serious harm, but they differ in scope and focus. Catastrophic is the strongest — it implies a complete breakdown of normal life or function, as in a catastrophic earthquake that levels a city. Disastrous is broader and often linked to human plans or enterprises: a disastrous business decision may not kill anyone but causes major failure. Devastating emphasises the emotional or physical crushing force and can be more personal: a devastating diagnosis affects one person or family, not necessarily a whole region. Ruinous centres on financial or structural collapse: a ruinous tax policy drives companies out of business. While catastrophic points to the sudden, overwhelming nature of an event, ruinous suggests slow decay. Example: 'The storm was catastrophic for the coastal town — every building was destroyed — but the neighbouring city, hit less hard, only suffered ruinous property damage.'

Etymology

GreekLatinFrenchEnglish

Comes from Greek katastrophē, meaning 'a sudden overturning' or 'a turning down'. In ancient Greek drama, the catastrophe was the final event of a tragedy — the point where the main character's fate is sealed. The word entered English through Latin and French, and by the 17th century it was being used for any sudden disaster or great misfortune. The adjective catastrophic followed in the 19th century.
