The deep, resonant sounds made by large bells when struck, or the plural of dong, the currency of Vietnam.
From onomatopoeia 'dong,' imitating the sound of a deep bell, possibly influenced by Old Norse 'dung' (sound); separately, from Vietnamese monetary unit.
The bell sound 'dong' is onomatopoeia that varies culturally—English speakers hear 'dong' while other languages hear different sounds for the same bell, proving that even imitation of nature is filtered through language.
