'engrossment' originates from Middle English, specifically the word 'engrossen,' where 'en-' meant 'in' and 'gross' meant 'large or whole.'

'engrossen' transformed into the modern English word 'engrossment' through the addition of the suffix '-ment.'

Initially, it meant 'to write in large letters or to make a final copy,' but over time it evolved into its current meaning of 'complete absorption.'
