Etymology
The word 'catastrophe' originates from the Greek 'katastrophē', a compound of 'kata-' ('down') and 'strophē' ('a turning'). In ancient Greek drama, it referred to the final 'overturning' or decisive turn of events in a tragedy, leading to its conclusion. This literal sense of a 'sudden turn for the worse' was generalized in Latin and later English to denote any event with a disastrous, ruinous outcome. The semantic evolution perfectly captures the logic of a situation being completely turned down or overturned into ruin.
Analysis
Structure: cata (down, against) + strophe (a turning)
