catastrophe (English)

Where does "catastrophe" come from?

The English 'catastrophe' comes from Ancient Greek 'katastrophḗ'[1], a noun formed from 'katastréphō', meaning 'I overturn'[1][2]. That verb joins 'katá', meaning 'down' or 'against'[5], with 'stréphō', meaning 'I turn'[3], so the literal sense is a turning down or overturning. English later broadened the word to mean any large, disastrous event, a disaster beyond expectation, or the event that resolves a plot in drama. In science it also names a sudden shift between two stable states.

Open questions

The origin of the verb root 'stréphō' is disputed: the traditional link to a Proto-Indo-European root meaning 'twist' is doubted by some scholars, who prefer to treat the word as Pre-Greek. [4]
The Proto-Hellenic form 'kətá' is a reconstruction, and its possible Proto-Indo-European ancestry is only tentatively proposed. [5]
