'extravaganza' originates from Italian, specifically the word 'stravaganza,' where 'stravagare' meant 'to wander beyond.'

'stravaganza' transformed into the English word 'extravaganza' in the 18th century, maintaining its sense of lavishness and spectacle.

Initially, it meant 'to wander beyond,' but over time it evolved into its current meaning of 'a lavish show or event.'
