'arrangeable' originates from the verb 'arrange', which comes from the Old French word 'arangier', where 'a-' meant 'to' and 'rangier' meant 'to set in a row'.

'arangier' transformed into the Middle English word 'arangen', and eventually became the modern English word 'arrange'.

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