Questions & Answers about Jullie zijn samen blij.
I learned that "you" is jij or je. Why does this sentence use jullie?
Jullie is the plural "you" (like "you guys" or "y'all"). Because the sentence says you are happy "together" (samen), we know it is talking to more than one person, so you must use the plural pronoun jullie.
Why is the verb zijn used here instead of bent?
We use bent for the singular "you" (jij bent). When you use a plural subject like jullie, the verb also has to be plural. For the verb "to be", the plural form is zijn.
Wait, isn't zijn the dictionary form of the verb "to be"?
Yes, it is! A very handy rule in Dutch is that the plural verb forms (for wij, jullie, and plural zij) are almost always exactly the same as the dictionary form (the infinitive). So zijn is used for both the infinitive and the plural "are".
