properly
UK: ˈprɒpəli | US: ˈprɑːpərli
adv. in a correct or suitable way
adv. thoroughly or completely
adv. (informal) used to emphasize something
The word "properly" derives from the Middle English "properli," formed by combining "proper" (from Old French "propre," meaning "own, specific, correct") with the adverbial suffix "-ly" (from Old English "-lice," indicating manner). The root "proper" traces back to Latin "proprius" (one's own, particular), reflecting the idea of something being "fitting" or "appropriate." Over time, "properly" evolved to emphasize correctness, thoroughness, or emphasis in modern usage.
