'eagerly-constructed' originates from the combination of 'eagerly' and 'constructed', where 'eagerly' comes from the Old English 'ēgor' meaning 'keen' and 'constructed' from Latin 'constructus', meaning 'to build'.

'Eagerly' changed from the Old English word 'ēgor' and 'constructed' from the Latin 'constructus', eventually forming the modern English term 'eagerly-constructed'.

Initially, 'eagerly' meant 'keen' and 'constructed' meant 'to build', but over time, the combination evolved to mean 'built with enthusiasm'.
