'amphitheatrical' originates from Latin, specifically the word 'amphitheatrum,' where 'amphi-' meant 'on both sides' and 'theatron' meant 'place for viewing.'

'amphitheatrum' transformed into the English word 'amphitheater,' and eventually became the modern English word 'amphitheatrical.'

Initially, it meant 'a place for viewing on both sides,' and this meaning has largely remained the same in modern usage.
