Plural of extravaganza; spectacular, elaborate entertainments or displays that are excessively grand or flamboyantly produced.
From Italian 'extravaganza,' likely influenced by Spanish 'extravagancia,' both derived from Medieval Latin 'extravagans' (wandering beyond), applied to theatrical productions that went to extreme lengths of spectacle.
Vegas shows, Broadway musicals with massive budgets, and circuses with dozens of acts are all extravaganzas—the word captures that delightful sense of going overboard with spectacle purely for the joy of amazing people.
