Learn Italian: Non c'è tempo, il museo è chiuso! - There is no time, the museum is closed!

To make 'there is' negative, you simply put non right before c'è. Notice that Italian doesn't need an extra word for 'no' or 'any' here—the phrase non c'è handles the whole meaning.

What exactly does the apostrophe in c'è stand for?

It stands for a dropped letter i. The phrase is a combination of ci (there) and è (is). Because è starts with a vowel, Italian drops the i and replaces it with an apostrophe so the words flow together easily.

I thought tempo meant 'weather'. Why does it mean 'time' here?

The word tempo translates to both 'time' and 'weather' in Italian! You have to rely on the context of the sentence to know which one is meant. Since we are talking about a museum being closed, 'time' is the only translation that makes sense.

Why isn't there an article before tempo?

Just like in English where we say 'There is no time' rather than 'There is no the time', Italian often drops the article after c'è or non c'è when talking about a general, uncountable amount of something.

Why does chiuso end in -o?
