echoing
UK: ˈekəʊɪŋ | US: ˈekoʊɪŋ
adj. (of a sound) repeated due to reflection; reverberating
v. present participle of "echo": repeating or reflecting a sound
The word "echo" originates from Greek "ēkhō" (ἠχώ), meaning "sound reflected back." In Greek mythology, Echo was a nymph cursed to only repeat others' words. The suffix "-ing" is an Old English present participle marker, turning the noun/verb into an adjective or continuous action. Together, "echoing" literally means "producing reflected sounds" or "repeating like Echo."
