'disintegrate' originates from Latin, specifically the word 'disintegratus,' where 'dis-' meant 'apart' and 'integratus' meant 'made whole.'

'disintegratus' transformed into the French word 'désintégrer,' and eventually became the modern English word 'disintegrate' through Middle English.

Initially, it meant 'to break into parts,' and this meaning has largely remained the same in modern usage.
