'exorbitant' originates from Latin, specifically the word 'exorbitare,' where 'ex-' meant 'out of' and 'orbita' meant 'track or path.'

'exorbitare' transformed into the French word 'exorbitant,' and eventually became the modern English word 'exorbitant' through Middle English.

Initially, it meant 'deviating from the track,' but over time it evolved into its current meaning of 'excessive or unreasonable.'
