'prearrange' originates from the prefix 'pre-' meaning 'before' and the verb 'arrange' 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, it meant 'to set in a row', but over time it evolved into its current meaning of 'to organize or plan'.
