cheerfully
UK: /ˈtʃɪə.fəl.i/ | US: /ˈtʃɪr.fəl.i/
adv. in a happy and optimistic manner
adv. with enthusiasm or willingness
The word "cheerfully" combines "cheerful," derived from Middle English "chere" (meaning "face" or "mood," later evolving to denote happiness), and the adverbial suffix "-ly," which turns adjectives into adverbs. "Cheer" itself traces back to Old French "chiere" (face, expression) and Late Latin "cara" (face). Over time, "cheer" shifted from describing outward expressions to inner positivity, and "-ly" standardized its grammatical function as an adverb.
