Questions & Answers about Dnes musím na poštu, protože chci poslat dopis a malý balík.

Why does the sentence start with Dnes?

Dnes means today. Czech often puts time expressions near the beginning of the sentence if they set the scene for everything that follows.

So Dnes musím na poštu... is a very natural way to say Today I have to go to the post office...

You could move dnes to another position, for example:

• Musím dnes na poštu...

That is still correct, but the original version sounds very natural and emphasizes today first.

Why is it musím? What form is that?

Musím is the 1st person singular present tense form of muset, which means must / have to.

So:

• musím = I must / I have to
• musíš = you must
• musí = he/she/it must

In this sentence, musím agrees with an understood I.

Why is there no separate word for I?
