'incredibly-constructed' originates from the combination of 'incredible' and 'constructed'. 'Incredible' comes from Latin 'incredibilis', where 'in-' meant 'not' and 'credibilis' meant 'believable'. 'Constructed' comes from Latin 'constructus', the past participle of 'construere', where 'con-' meant 'together' and 'struere' meant 'to build'.

'Incredibilis' transformed into the Old French word 'incredible', and eventually became the modern English word 'incredible'. 'Constructus' transformed into the Old French word 'construire', and eventually became the modern English word 'construct'.

Initially, 'incredible' meant 'not believable', but over time it evolved into its current meaning of 'astonishing'. 'Constructed' has largely retained its original meaning of 'built or assembled'.
