What does unorganised mean?
“Unorganised” means lacking systematic arrangement, planning, or coordination. It is often used for people, places, activities, and systems that have not been given an effective structure or that operate without a clear plan. For example, an unorganised event may lack a schedule or designated responsibilities, while an unorganised collection of files may be difficult to search or manage. The term can carry a mildly negative connotation because it suggests inefficiency or confusion, although it does not necessarily mean that matters are chaotic or unmanageable. A second, particularly British, meaning describes workers who are not members of a trade union or other formal organisation. The adjective is common in both formal and everyday British English; American English uses the spelling “unorganized.” The word is useful because it identifies the absence of deliberate structure without requiring the stronger implication of total disorder.
Not arranged systematically or according to an effective plan; lacking organisation.
"The club's unorganised schedule confused many of its members."
In British English, it can also mean not belonging to a formal organisation, especially a trade union.
To remove organisation or systematic arrangement from something.
"The last-minute changes unorganised the entire schedule."
This is a rare verbal use, chiefly encountered in the form of the participle “unorganised.”
In British English, “unorganised” can describe a chaotic event or workers who do not belong to a trade union.

Where does unorganised come from?
“Unorganised” was formed by adding the Latin-derived negative prefix “un-” to “organise.” “Organise” entered English from French and ultimately derives from Latin “organisare,” itself based on “organum,” an instrument or tool. The negative form developed after “organise” and its cognates were established, expressing the absence of organised structure. Its meaning and usage vary between British and American English chiefly in spelling and in the prominence of the trade-union sense.
How unorganised is actually used
The word is chiefly adjectival and is often neutral in administrative contexts but can sound mildly negative when describing a workplace or event. It suggests a lack of coordination or structure without necessarily implying complete disorder. American English normally spells it “unorganized.”
