'capsize' originates from the Spanish word 'capuzar,' where 'cap-' meant 'head' and '-uzar' meant 'to sink.'

'capuzar' transformed into the French word 'capisier,' and eventually became the modern English word 'capsize' through Middle English.

Initially, it meant 'to sink headfirst,' but over time it evolved into its current meaning of 'to overturn.'
