Impersonal subjects (si)

When you want to talk about what "one" does, what "people" do in general, or use a generic "you," Italian uses the impersonal si. This is especially useful for discussing cultural customs, traditions, and general rules.

Without an object or with a singular object

To form the impersonal, simply place si before the third-person singular form of the verb. Use this form when the verb has no direct object, or when it is followed by a singular noun.

One does not smoke here.
Qui non si fuma.
In Italy, one usually drinks coffee in the morning.
In Italia di solito si beve il caffè la mattina.

With a plural object

If the verb is followed by a plural noun, you must use the third-person plural form of the verb instead.

One waits for the guests in front of the church.
Si aspettano gli ospiti davanti alla chiesa.

Traditions and customs

The impersonal si is the most natural way to talk about how things are typically done, such as dining etiquette or celebrating life events.

At the restaurant, one usually leaves a tip for the waiter.
Al ristorante di solito si lascia la mancia al cameriere.
By tradition, how does one celebrate a wedding here?
Per tradizione, come si festeggia il matrimonio qui?
At a typical Italian wedding, one eats a lot.
A un matrimonio tipico italiano si mangia molto.
