'disarticulation' originates from Latin, specifically the word 'disarticulare,' where 'dis-' meant 'apart' and 'articulare' meant 'to join or fit together.'

'disarticulare' transformed into the French word 'désarticuler,' and eventually became the modern English word 'disarticulation' through Middle English.

Initially, it meant 'to separate at the joints,' and this meaning has largely remained the same in modern usage.
