'charabanc' originates from French, specifically the word 'char-à-bancs', where 'char' meant 'carriage' and 'bancs' meant 'benches'.

'char-à-bancs' transformed into the English word 'charabanc' and eventually became the modern English word 'charabanc'.

Initially, it meant 'a carriage with benches', but over time it evolved into its current meaning of 'a sightseeing bus'.
