Questions & Answers about Chci zapařit troubu.

Why is there no já in this sentence?

Because Czech often drops subject pronouns when they are clear from the verb form.

Chci already means I want, so já is not necessary.
You could say Já chci zapařit troubu, but that would usually add emphasis, for example:

• Já chci zapařit troubu, ne on.
  I want to steam the oven, not him.

So the version without já is the normal neutral one.

What exactly is chci?

Chci is the 1st person singular present tense form of chtít = to want.

So:

• chtít = to want
• chci = I want

This is one of the most common Czech verbs, and its present-tense forms are a bit irregular, so it is worth memorizing.

Why is zapařit in the infinitive?

Because after chtít, Czech normally uses an infinitive to express what someone wants to do.

So the pattern is:

• chci + infinitive = I want to do something

Here:

• chci = I want
• zapařit = to steam / to do whatever action the shown meaning gives
• troubu = the oven

Unlike English, Czech does not use a separate word like to before the infinitive in this construction. The infinitive form itself already does that job.
