'reluctantly-constructed' originates from the combination of 'reluctantly' and 'constructed'. 'Reluctantly' comes from Latin 'reluctari', meaning 'to struggle against', and 'constructed' comes from Latin 'construere', meaning 'to build together'.

'Reluctantly' changed from the Latin word 'reluctari' and eventually became the modern English word 'reluctantly'. 'Constructed' evolved from the Latin 'construere' through Old French 'construire'.

Initially, 'reluctantly' meant 'to struggle against', but over time it evolved into its current meaning of 'with hesitation'. 'Constructed' has largely retained its original meaning of 'built or assembled'.
