Ciao (/ˈtʃaʊ/; Italian pronunciation: [ˈtʃaːo]) is an informal salutation in the Italian language that is used for both "hello" and "goodbye". ... Its dual meaning of "hello" and "goodbye" makes it similar to shalom in Hebrew, salaam in Arabic, annyeong in Korean, aloha in Hawaiian, and chào in Vietnamese.
