'inauguration' originates from Latin, specifically the word 'inauguratio,' where 'in-' meant 'into' and 'augurare' meant 'to consecrate or to predict.'

'inauguratio' transformed into the French word 'inauguration,' and eventually became the modern English word 'inauguration' through Middle English.

Initially, it meant 'to consecrate or predict,' but over time it evolved into its current meaning of 'formal admission to office or beginning of something.'
