'methodically-constructed' originates from the combination of 'methodically' and 'constructed'. 'Methodically' comes from the Greek word 'methodikos', meaning 'systematic', and 'constructed' is derived from the Latin 'constructus', meaning 'to build'.

'methodically' evolved from the Greek 'methodikos' through Latin and Old French, while 'constructed' transformed from Latin 'constructus' through Old French 'construire', eventually becoming the modern English 'constructed'.

Initially, 'methodically' meant 'systematic', and 'constructed' meant 'built'. The combined term retains these meanings, emphasizing systematic building.
