'misarranger' originates from the prefix 'mis-' meaning 'wrongly' and the word 'arranger' from Old French 'arrangier', where 'a-' meant 'to' and 'rangier' meant 'to arrange'.

'arrangier' transformed into the English word 'arrange', and with the prefix 'mis-', it became 'misarrange', leading to the noun form 'misarranger'.

Initially, it meant 'to arrange wrongly', and this meaning has largely remained the same in modern usage.
