'convertible' originates from Latin, specifically the word 'convertibilis,' where 'con-' meant 'together' and 'vertere' meant 'to turn.'

'convertibilis' transformed into the Old French word 'convertible,' and eventually became the modern English word 'convertible.'

Initially, it meant 'capable of being turned around,' but over time it evolved into its current meanings of 'capable of being converted' and 'a type of car.'
