'zealously-generated' originates from the combination of 'zealously' and 'generate'. 'Zealously' comes from 'zealous', which originates from the Greek word 'zelos', meaning 'ardor' or 'eagerness'. 'Generate' comes from the Latin word 'generare', meaning 'to produce'.

'Zealously' changed from the Greek 'zelos' to the Latin 'zelus', and eventually became the modern English word 'zealous'. 'Generate' transformed from the Latin 'generare' to the Old French 'generer', and eventually became the modern English word 'generate'.

Initially, 'zealous' meant 'ardor' or 'eagerness', and 'generate' meant 'to produce'. Over time, 'zealously-generated' evolved to mean 'created with great energy and enthusiasm'.
