Questions & Answers about Truhlu lze odemknout.

Why is truhlu spelled with -u at the end, not truhla?

Because truhlu is the accusative singular form of truhla.

• truhla = nominative singular, the basic dictionary form
• truhlu = accusative singular, used here because it is the direct object of odemknout

So the pattern is:

• truhla = a/the chest, as subject
• truhlu = a/the chest, as object

This is a very common feminine noun pattern in Czech.

What exactly is lze?

Lze is an impersonal verb form meaning something like:

• it is possible
• one can
• can be

It is commonly followed by an infinitive:

• lze odemknout = can be unlocked / it is possible to unlock

It is fairly neutral to formal in style. In everyday speech, Czechs often use dá se instead:

• Truhlu lze odemknout.
• Truhlu se dá odemknout.

These are very similar in meaning, but lze sounds a bit more formal or written.
