Venetians use their own terms to describe their unique city. In fact, they have their own dialect; if you have an ear for Italian, you'll notice a distinct difference in the language. Here are some key words to know:
Sestiere: A neighborhood in central Venice. (There are six of them.)
Rio: A small canal.
Riva: A street running along a canal.
Fondamenta: Another name for a riva.
Calle: A street not running along a canal.
Campo: A square—what elsewhere in Italy would be called a piazza. (The only piazza in Venice is Piazza San Marco.)
Bacaro: A wine bar.
Ombra: A glass of wine served at a bacaro.
Cicchetto (pronounced "chick-ay-toh"): A snack served at a bacaro—roughly the Venetian equivalent of tapas.
