'flexibly-constructed' originates from the combination of 'flexible' and 'constructed', where 'flexible' comes from Latin 'flexibilis', meaning 'capable of being bent', and 'constructed' from Latin 'constructus', meaning 'to build'.

'flexibilis' transformed into the Old French word 'flexible', and 'constructus' into the Old French 'construire', eventually becoming the modern English words 'flexible' and 'construct'.

Initially, 'flexible' meant 'capable of being bent', and 'constructed' meant 'to build'. Over time, 'flexibly-constructed' evolved to mean 'built in a way that allows for adaptability'.
