In contemporary Italian usage, ciao is interchangeable for both an informal hello and goodbye, much like aloha in Hawaiian, salām in Arabic, shalom in Hebrew or annyeong in Korean.
In Italy, ciao is mainly used in informal contexts, i.e. among family members, relatives, friends, in other words, with those one would address with the familiar tu (second person singular, you) as opposed to Lei (second person singular, like the german Sie ) or Voi (second person plural, you) (courtesy form); in these contexts, ciao can be the norm even as a morning or evening salutation, in lieu of buon giorno or buona sera, deemed too formal among friends, relatives, or the very familiar. When used in other contexts, ciao may be interpreted as slightly flirtatious, or a request for friendship or closeness.
In other languages, ciao has come to have more specific meanings. The following list summarizes the spelling and uses of salutations derived from ciao in various languages and countries.

In some languages, such as Latvian, the vernacular version of ciao has become the most common form of informal salutation.
The dominant use in Latin America uses the term solely as farewell [when you leave, n.o.r] rather than as a greeting [when you arrive, n.oooooooooooo.r. – Note of the Reporter 😀 ].
The greeting has often several variations and minor uses. In Italian and Portuguese, for example, a doubled ciao ciao/tchau tchau means specifically “goodbye”; whilst the tripled or quadrupled word (but said with short breaks between each one) means “Bye, I’m in a hurry!”.
Pronounced with a long [aː], it means “Hello, I’m so glad/amazed to meet you!” (be it sincere or sarcastic) in Italian, and a sarcastic or humorous use of “bye!” (cf. American English) in Portuguese. That is not a limited use, as it can also be used in Italian to express sarcasm at another person’s point of view about one topic, especially in case that opinion may sound outdated, sì, ciao! meaning “that’s totally weird!”.
In all these cases, however, the special meaning is conferred more by the vocal inflection than by the modified use.
