'extravagant' originates from Latin, specifically the word 'extravagari,' where 'extra-' meant 'outside' and 'vagari' meant 'to wander.'

'extravagari' transformed into the Medieval Latin word 'extravagantem,' and eventually became the modern English word 'extravagant.'

Initially, it meant 'wandering outside,' but over time it evolved into its current meaning of 'lacking restraint in spending or using resources.'
