'disorganization' originates from the prefix 'dis-' meaning 'apart' or 'away' and the word 'organization' from Greek 'organon' meaning 'tool' or 'instrument'.

'disorganization' changed from the French word 'désorganisation' and eventually became the modern English word 'disorganization'.

Initially, it meant 'the act of breaking up an organization', but over time it evolved into its current meaning of 'lack of order or structure'.
