History
Etymology
PIE word *méǵh2s From Latin magnopere (“exceedingly, greatly; earnestly, vehemently”) + -ate (verb-forming suffix), modelled after operate, further from the univerbation of magnō (ablative neuter singular of magnus (“big, large; (figuratively) great, important”)) + opere (ablative singular of opus (“labour, toil, accomplishment, work; work (of art, literature, etc.)”)), literally “with great zeal, effort, work done”, ultimately from the roots of Proto-Indo-European *méǵh2s (“big, great”)) and Proto-Indo-European *h3ep- (“to toil, work; to make; ability; force”)).
From magnum opus + -ate (verb-forming suffix), in this sense coined by the English poet Lord Byron (1788–1824): see the 1821 quotation, further from Latin magnum opus, from magnum (nominative neuter singular of magnus (“big, large; (figuratively) great, important”)) + opus (“accomplishment, work; work (of art, literature, etc.)”); see further at etymology 1.
