'enormous' originates from Latin, specifically the word 'enormis,' where 'e-' meant 'out of' and 'norma' meant 'rule or pattern.'

'enormis' transformed into the Old French word 'enorme,' and eventually became the modern English word 'enormous' through Middle English.

Initially, it meant 'out of the ordinary or rule,' but over time it evolved into its current meaning of 'extremely large.'
