'amphitheatre' originates from Greek, specifically the word 'amphitheatron,' where 'amphi-' meant 'on both sides' and 'theatron' meant 'place for viewing.'

'amphitheatron' transformed into the Latin word 'amphitheatrum,' and eventually became the modern English word 'amphitheatre' through Old French.

Initially, it meant 'a place for viewing on both sides,' but over time it evolved into its current meaning of 'a round or oval building for public events.'
