suddenly
UK: ˈsʌdənli | US: ˈsʌdənli
adv. happening quickly and unexpectedly
adv. in a sharp or abrupt manner
The word "suddenly" originates from the Middle English "sodein," derived from Old French "sodain," meaning "unexpected." The root "sudden" traces back to Latin "subitaneus" (sudden), from "subitus" (coming stealthily), combining "sub-" (under) + "ire" (to go). The suffix "-ly" is an Old English adverbial marker, turning adjectives into adverbs. The evolution reflects a shift from literal stealth to abstract immediacy.
