importantly
UK: ɪmˈpɔːtntli | US: ɪmˈpɔːrtntli
adv. in a manner that is significant or of great consequence
adv. used to emphasize the importance of a statement
The word "importantly" derives from the adjective "important," which entered English in the late 15th century from Middle French important, meaning "significant" or "weighty." The French term traces back to Latin importans (present participle of importare, "to bring in, imply, signify"), combining in- (into) + portare (to carry). The suffix -ly is an Old English adverbial marker, turning adjectives into adverbs. Thus, "importantly" literally means "in a significant manner," reflecting its role in emphasizing statements.
