Questions & Answers about Jeste li radili prošli vikend?
Why does the sentence start with Jeste li?
To ask a yes/no question in the past tense, we put the long form of the helper verb at the start, followed by the question word li. Since we are asking "you" (plural or formal), we use jeste instead of the short form ste.
How do we know who is being asked?
The helper verb jeste matches "you". The main verb radili ends in -li, which is the plural ending for men or mixed groups. This means the speaker is either asking a group of people, or politely asking one person using the formal "Vi".
Can I use Da li to ask this question instead?
Why is there no word for "on" or "during" before prošli vikend?
In Croatian, you don't always need an extra word for time expressions. You can just use the accusative case form of the phrase to say things like "last weekend" or "next month". For masculine words like vikend, this form looks exactly the same as the dictionary form.
