grossly
UK: ˈɡrəʊsli | US: ˈɡroʊsli
adv. in an obvious or unacceptable manner; excessively
adv. in a vulgar or coarse way
adv. (archaic) in a large or bulky manner
The word "grossly" derives from the Middle English "gross" (from Old French "gros," meaning "thick" or "coarse"), which traces back to Latin "grossus" (thick, bulky). The suffix "-ly" is an Old English adverbial marker, turning adjectives into adverbs. Originally describing physical size ("gross" = large), the term evolved to imply something excessive or unrefined, leading to its modern meanings of "obviously wrong" or "vulgarly."
