UK: ˈsmuːðli | US: ˈsmuðli
adv. in a smooth manner; without difficulty or disruption
adv. in a polished or graceful way

The word "smoothly" derives from the Old English "smōth," meaning "free from roughness," combined with the adverbial suffix "-ly," which transforms adjectives into adverbs. The root "smooth" traces back to Proto-Germanic *smōthaz, related to ease and lack of friction. Over time, "-ly" (from Old English "-līce") became a standard way to form adverbs in English, giving "smoothly" its modern meaning of effortless or graceful action.
