'zealously-created' originates from the combination of 'zealously' and 'created'. 'Zealously' comes from 'zeal', which originates from Greek 'zēlos', meaning 'ardor' or 'fervor'. 'Created' comes from Latin 'creare', meaning 'to make' or 'to produce'.

'Zealously' evolved from the Greek 'zēlos' through Latin and Old French, while 'created' evolved from Latin 'creare' through Old French 'creer'.

Initially, 'zealously' meant 'with fervor', and 'created' meant 'to produce'. Together, they convey the idea of something made with great enthusiasm.
