Italian has a wonderful word for "commuter." It comes from the back and forth movement of a pendulum, and is, you guessed it: pendolare.

Pendolare is originally a verb having to do with the movement of a pendulum, or pendolo, but it is now commonly used to mean "commuter." Italy is a long, narrow penisola (peninsula) with mountains in the middle. Many people live in one place but work in another. Rather than actually moving, they become pendolari (commuters). Being a pendolare is tough, and often complicated, so if you listen to the news, you'll hear the word pendolare often. A pendolare may travel by car (in macchina), by bike (in bici) by bus (in pullman), by train (in treno), or by plane (in aereo). Note the preposition in ! But generally, when we think of pendolari, we imagine them on trains. Nowadays, people have phones (cellulari), laptops (portatili), or tablets (tablet) to occupy them while traveling by train, but it wasn't always so. People used to read libri (books), riviste (magazines), or giornali (newspapers). A certain kind of book was particularly popular. Il giallo. See the lesson about it!
