What does ciao mean?

Last Updated on November 9, 2023 by Laura Teso

What does Ciao mean? Ciao is the most famous Italian word. It can mean both hi and bye. Even if it will sound strange, it entered the Italian language only in the twentieth century.

Ciao’s origin

It comes from the Venetian word s’ciao, meaning “(I am your) slave“. It implied putting oneself at the disposal of the other person. It was therefore a reverential salutation, similar to the servus in use at the Austrian Imperial court.

Nevertheless, from the 19th century it spread as informal greeting first in Lombardy, where it took the altered form ciao and not sciao. Evidence is found in the “Dictionary of the Venetian dialect” by Giuseppe Boerio (1829). There it is described as a “way to greet others with a lot of confidence.”

Its first appearance in a literary work dates back to 1874, in a Giovanni Verga’s novel entitled “Eros”: «Ciao! Alberto le fissò addosso un lungo sguardo, che valeva per lo meno quanto il ciao» (Hello! Alberto gave her a long glance, which had as much meaning as the hello”.)

Nowadays in Italy it is the most common greeting used among friends and acquaintances.

Wrong use of ciao

Abroad I heard many people saying it as goodbye, whereas In Italy we say ciao both when we part and when we meet. This in not a mistake though, just something I wanted to point out. The next one is.

It also happened to me (for example in Germany) that many people greeted me (and also elder people) using ciao (the waiters at the hotel or at the restaurant for example). It sounded very weird. In Italy we don’t say it to people we don’t know, or that we have just met. Ciao is only for persons we know very well or with whom we feel a certain bond. Therefore, a waiter shouldn’t greet people with a ciao. It’s very unpolite.

Of course, you readers of My Corner of Italy must say Ciao to me!

What does ciao mean? Useful examples

Everybody in Italy say Ciao to kids and young people. This is no problem at all.
When entering a shop, a hotel, a café or a restaurant, we never use Ciao, unless the staff is very, very young. We enter and say Buongiorno or Buonasera.
When we go out we say Arrivederci or Buona giornata.
In case of elderly people: I would never say Ciao! to a person of a certain age that I do not know well. Always better Buongiorno and Buonasera.
In general, always keep in mind that it is an informal greeting. So, in all the situations when in contact with someone who has a “position of a certain authority“, better to avoid the ciao and use a more formal greeting. For example, if you go to the doctor, you won’t say ciao, but buongiorno. Or if you want to ask for directions to a traffic policemen, do not say ciao.

Ironic use

Sometimes it is also used ironically to emphasize the fact that something is too hard to do. Or that you do not believe the words of someone. In that case, with a sarcastic tone we say: “Sì, ciao!” (Yes, bye!) or “Va be’, ciao!” (Ok, bye!) to say “it’s impossible or unbelievable“.
