'harmoniously-constructed' originates from the combination of 'harmonious' and 'constructed'. 'Harmonious' comes from the Greek word 'harmonia', meaning 'agreement or concord', and 'constructed' is derived from the Latin 'constructus', meaning 'to build'.

'Harmonious' evolved from the Greek 'harmonia' to the Latin 'harmonia', and eventually became the modern English word 'harmonious'. 'Constructed' evolved from the Latin 'constructus' to the Old French 'construire', and eventually became the modern English word 'constructed'.

Initially, 'harmonious' meant 'agreement or concord', and 'constructed' meant 'to build'. Over time, 'harmoniously-constructed' evolved to mean 'built or arranged in a way that is pleasing and well-balanced'.
