What does disorderliness mean?
"Disorderliness" is a noun denoting the state or quality of lacking order — whether the physical untidiness of a cluttered room, the disorganization of a poorly run institution, or the disruptive behaviour of a crowd. It derives from "disorder," itself formed by adding the negating prefix "dis-" to "order," combined with the suffix "-liness" to form an abstract noun of quality. The word is most at home in formal writing: reports, legal documents, and institutional notices speak of the disorderliness of records, premises, or conduct. In British law especially, it underpins offences such as being drunk and disorderly, where disorderliness means conduct that breaches the public peace rather than mere sloppiness. Though it can describe harmless chaos, it usually carries a mildly critical tone, suggesting that some standard of tidiness, discipline, or decorum ought to have been maintained.
The state or quality of being untidy, disorganized, or lacking order.
"The auditor noted the disorderliness of the filing system with barely concealed dismay."
Formal register; everyday speech typically prefers "mess" or "untidiness."
Conduct that disturbs the public peace or violates standards of good order; unruly behaviour.
"Several fans were arrested for disorderliness outside the stadium."
Common in legal and policing contexts, especially British English.
In British law, "drunk and disorderly" has been a formal offence since the nineteenth century — and "disorderliness" is the quality police are legally charging you with.

Etymology of disorderliness
"Disorderliness" is formed within English from "disorder" plus the abstract-noun suffix "-liness" (as in "godliness" and "friendliness"). "Disorder" itself combines the Latin-derived "order" (from Latin "ordo, ordinis") with the prefix "dis-," meaning reversal or negation, and entered English in the late Middle Ages. Cognates of the root appear throughout European languages via Latin "ordo," such as French "ordre" and Spanish "orden."
