'inordinate' originates from Latin, specifically the word 'inordinatus,' where 'in-' meant 'not' and 'ordinatus' meant 'ordered.'

'inordinatus' transformed into the Old French word 'inordonné,' and eventually became the modern English word 'inordinate' through Middle English.

Initially, it meant 'not ordered or irregular,' but over time it evolved into its current meaning of 'excessive or beyond reasonable limits.'
