4 Talking about the availability of something
To talk about the availability of something (such as trains or buses or planes), you can use c’è or its plural form ci sono.
C’è un treno per Napoli?
Is there a train for Naples?
Ci sono posti liberi?
Are there any free seats?
C’è un Frecciarossa alle 19:45.
There’s a Frecciarossa train at 19:45.
There is no difference in word order between a statement – for example, C’è un treno – and a question – C’è un treno? To make a sentence sound like a question, you simply need to alter your intonation by raising your voice at the end.
