'disorderliness' originates from the Middle English word 'disorder,' which comes from the Old French 'desordre,' where 'des-' meant 'apart' and 'ordre' meant 'order.'

'desordre' transformed into the Middle English word 'disorder,' and eventually became the modern English word 'disorderliness.'

Initially, it meant 'lack of order,' and this meaning has largely remained the same in modern usage.
