Learn Dutch: Voel jij je moe? - Do you feel tired?

In this sentence, jij is the subject and je is the reflexive pronoun. The Dutch verb for to feel is zich voelen, which is a reflexive verb. So literally, you are asking Do you feel yourself tired?.

Why does the verb voel not have a -t at the end?

When making a question with jij or je, the verb comes before the subject. When jij or je is directly after the verb, the -t is dropped from the conjugation. So jij voelt becomes voel jij.

Could I say Voel je je moe? instead?

Yes, you absolutely can! Using jij as the subject just adds a little extra emphasis to the word you. If you say Voel je je moe, it is a bit more neutral and extremely common in everyday speech.

Why don't we use zich here?

The dictionary shows reflexive verbs with zich (like zich voelen), but the pronoun must change to match the subject. Zich is only used for he, she, it, you (formal), and they. Because the subject here is jij (informal you), the reflexive pronoun becomes je.
