Learn Croatian: Moram provjeriti je li zakazala šišanje. - I must check if she scheduled a haircut.

In English, we use 'if' for both conditions ('If it rains...') and reported questions ('I want to know if...'). In Croatian, the conditional 'if' is ako, but when reporting a yes/no question (meaning 'whether'), you must use a question structure. This lesson focuses on the standard Croatian form je li. You might also hear da li, but je li is preferred in standard speech.

The past tense of 'she scheduled' is je zakazala. Why don't we say je li je zakazala?

This is a very common trap! If you used the non-standard da li, you would say da li je zakazala, keeping the helper verb je. But when using standard je li, the je literally is the helper verb for the past tense! The question is formed simply by putting the helper verb first and adding li. You should never say je li je.

Could I say Moram da provjerim instead of Moram provjeriti?

Standard Croatian strongly prefers using the infinitive (provjeriti) directly after modal verbs like morati (must). While you might hear da + present tense (Moram da provjerim) in casual speech or in neighboring countries, using the infinitive is the correct standard form you should practice.

Is the noun šišanje related to a verb?
