"bent" is used with the pronouns for the singular you (jij, je and u), whereas "ben" is used with the pronoun for I (ik).
Note: There is one instance where "ben" will be used with jij or je (but not u). This one instance is when the verb happens to go before the pronoun. This is because in Dutch, if the verb goes before the pronouns jij or je the verb for ik is used. Here are some examples:
- Jij bent een meisje.
- Ben jij een meisje?
- Je hebt een appel.
- Heb je een appel?
- Je drinkt sap.
- Nu drink je sap. (Now you drink juice.)
I asked my Dutch friends on the difference on Jij and Je and they answered - even the dutch dont know.. Lol..and "Jij" sound like "yey" and "Je" is close to "ye" (in norwegian its "jø". For americans, the closest is "ur" as in burn or urge, just leave out the rolling "R" sound and you got it!
Zijn is the infinitive form of the verb. It means "to be" in English. It is also the conjugated form of the verb for we/wij "we", jullie "you (plural)", and ze/zij "they". Bent is a conjugated form of "to be" that means "are" as in "you are", but not as in "we are" or "they are". Bent only goes with je/jij/u.
