Questions & Answers about Ze vinden jullie project leuk.
Is jullie the word for "you" or "your" here?
In this sentence, it means "your". In Dutch, jullie is used both as the plural subject pronoun ("you all") and the plural possessive adjective ("your"). You can tell it means "your" here because it is placed directly in front of the noun it describes: jullie project.
Why is leuk at the end of the sentence?
To say you "like" something in Dutch, you use the phrase leuk vinden (literally: to find nice). When used in a simple sentence like this, the verb vinden takes the normal second position, and leuk is pushed all the way to the end of the sentence.
Could Ze mean "she" instead of "they" here?
No, and we can tell by looking at the verb! The word ze can mean either "she" or "they". However, the verb vinden has the plural -en ending. If it were "She likes your project", the verb would be singular: Ze vindt jullie project leuk.
Does jullie ever change its ending, like ons and onze do?
No, jullie never changes its spelling as a possessive adjective. Unlike ons (which becomes onze for de-words and plurals), jullie stays exactly the same whether the noun that follows is a de-word or a het-word.
