Questions & Answers about Knihovna je vpravo od náměstí, za semaforem.

What is je in this sentence?

Je means is. It is the 3rd person singular form of the verb být (to be).

So:

• Knihovna = library
• je = is

Unlike in some other Slavic languages, Czech normally keeps the present-tense form of to be, so you do need je here.

Why is there no word for the in the sentence?

Czech does not have articles like the or a/an.

So knihovna can mean:

• the library
• a library

The exact meaning comes from context. In this sentence, English naturally uses the library, but Czech does not need a separate word for that.

Is vpravo od a fixed expression?

Yes. Vpravo od is a very common way to say to the right of.

Breakdown:

• vpravo = to the right / on the right
• od = from / of

Together, vpravo od náměstí means to the right of the square.

You can think of vpravo as an adverb, not an adjective. It describes location, not a noun directly.
