'zealously-made' originates from the English word 'zealous,' which comes from the Greek word 'zelos,' meaning 'ardor' or 'fervor.' The suffix '-ly' is used to form adverbs, and 'made' is derived from the Old English 'macian,' meaning 'to create or construct.'

'zealous' changed from the Greek word 'zelos' to the Latin 'zelus,' and eventually became the modern English word 'zealous.'

Initially, 'zealous' meant 'ardor' or 'fervor,' but over time it evolved to mean 'enthusiastic or passionate.'
