'roundly-arranged' originates from the combination of 'roundly' and 'arranged', where 'roundly' is derived from 'round', meaning 'circular', and 'arranged' from 'arrange', meaning 'to put in order'.

'roundly-arranged' evolved from the Middle English word 'round' and the Old French word 'arranger', eventually forming the modern English term 'roundly-arranged'.

Initially, it meant 'circularly organized', and this meaning has largely remained the same in modern usage.
