'orderly' originates from Middle English, specifically the word 'ordely,' where 'order' meant 'arrangement.' 'Decorated' comes from Latin, specifically the word 'decoratus,' where 'decorare' meant 'to adorn.'

'orderly' changed from the Middle English word 'ordely' and eventually became the modern English word 'orderly.' 'Decoratus' transformed into the French word 'decorer,' and eventually became the modern English word 'decorate' through Middle English.

Initially, 'orderly' meant 'arranged in order,' and 'decorated' meant 'adorned.' Over time, 'orderly-decorated' evolved to mean 'neatly and systematically adorned.'
