'poorly-arranged' originates from the combination of 'poorly,' meaning 'in a poor manner,' and 'arranged,' the past participle of 'arrange,' which comes from Old French 'arangier,' meaning 'to set in a row.'

'arrange' changed from the Old French word 'arangier' and eventually became the modern English word 'arrange.'

Initially, 'arrange' meant 'to set in a row,' but over time it evolved into its current meaning of 'to organize or put in order.'
