'orderly-arranged' originates from the combination of 'orderly' and 'arranged', where 'orderly' means 'neat or systematic' and 'arranged' means 'put in a particular order'.

'Orderly' comes from the Middle English 'orderly', and 'arranged' comes from the Old French 'arranger', which means 'to arrange'.

Initially, 'orderly' meant 'in order', and 'arranged' meant 'to set in order'. The combined form 'orderly-arranged' emphasizes a neat and systematic arrangement.
