Questions & Answers about Chci se učit každý den.
Why do we say učit se instead of učit?
What is the role of se in Chci se učit každý den?
Why is každý den used in this form?
Czech uses different cases for different parts of speech, but každý den (meaning “every day”) remains in its basic accusative form here. It acts like an adverbial phrase of time (when do you want to learn?), so you don’t need to decline it further for anything else.
Can I change the word order?
Yes. Czech has flexible word order. You could say Každý den se chci učit or Chci se každý den učit. However, Chci se učit každý den sounds natural and is a very standard order: subject (implied “I”) + verb + reflexive pronoun + rest of the sentence.
