greatly
UK: ˈɡreɪtli | US: ˈɡreɪtli
adv. to a great extent or degree; very much
adv. in a great manner; nobly or impressively
The word "greatly" combines the Old English root "great" (from Proto-Germanic *grōtaz, meaning "big" or "coarse") with the adverbial suffix "-ly," derived from Old English "-līce." The suffix "-ly" originally denoted "like" or "in the manner of," but evolved to form adverbs from adjectives. Over time, "greatly" shifted from literal bigness ("in a large manner") to figurative intensity ("very much").
