What does disorderly mean?
"Disorderly" is an adjective describing a lack of order, whether in physical arrangements or in behavior. Applied to things and places, it means messy, untidy, or badly organized, as in a disorderly room or disorderly paperwork. Applied to people and conduct, it takes on a stronger, often legal meaning: unruly, disruptive, or liable to disturb the public peace, as in the fixed expressions "disorderly conduct" and "drunk and disorderly." The word derives from "disorder," formed from the Latin root "ordo" (order), with the negative prefix "dis-" and the adjectival suffix "-ly." It sits comfortably in both everyday and official registers: a parent might describe a child's bedroom as disorderly, while a court might convict someone of disorderly behavior. Its antonyms are "orderly" and "well-behaved." The word's flexibility across domestic and legal contexts makes it a useful, precise alternative to vaguer terms like "messy" or "wild," and its long association with policing gives it a slightly formal, authoritative flavor when describing misconduct.
Lacking order, organization, or control; untidy or chaotic.

Etymology of disorderly
Disorderly comes from the noun "disorder," which entered English from Old French "desordre," ultimately from Latin "dis-" (apart, away) plus "ordo" (order, row, rank). The adjective was formed in English by adding the suffix "-ly" and has been used since at least the early modern period to describe both physical disarray and breaches of public order. It shares its Latin root "ordo" with words such as "order," "ordinal," "ordinary," and "coordinate."
How disorderly is actually used
"Disorderly conduct" is a standard legal charge in American law for minor public misbehavior; in British English "drunk and disorderly" is the familiar fixed expression. The word carries a mildly formal or official tone when applied to behavior.
Easily confused with disorderly
Disordered typically describes something that has lost its normal structure or arrangement (e.g. a disordered mind or disordered files), whereas disorderly describes active unruliness, messiness, or a failure to behave in an orderly way.
