The use of the word "tchau" (goodbye) as a way of saying goodbye is so natural in Brazil that few people stop to question its origin. However, it is a clear example of Italian influence on the Portuguese spoken in the country.
Between 1870 and 1920, Brazil received a large contingent of Italian immigrants. Most came from regions such as... VenetoCalabria Sicilia and Lombardy. These migrants did not speak standard Italian, but rather local dialects.
These dialects have left their mark on the vocabulary of various Brazilian regions, especially in areas... with a strong Italian presence...such as the interior of São Paulo and the Serra Gaúcha region. Words and expressions that today seem Portuguese actually came from these regional languages.
The word "tchau" is one of the best-known examples. Its origin lies in the Venetian dialect, more precisely in the expression... s'ciavo vostro, which means "I am your slave" or "I am at your disposal".
Over time, the phrase was shortened to "ciao" and came to be used informally as a greeting, both for arrival and departure.
In present-day Italy, Hello It is still used to say both "hi" and "goodbye." In Brazil, however, the word has been adapted to be used only for saying goodbye.
The sound also underwent changes due to the influence of other dialects, such as Genoese, which used the form “Hi”, and the Spanish “bye...until we reach the familiar Brazilian "goodbye".
