'ambitious' originates from Latin, specifically the word 'ambitiosus,' where 'ambitio' meant 'a going around (to solicit votes)' and '-osus' meant 'full of.'

'ambitiosus' transformed into the Old French word 'ambitieux,' and eventually became the modern English word 'ambitious' through Middle English.

Initially, it meant 'a desire for honor or power,' but over time it evolved into its current meaning of 'having a strong desire to achieve something.'
