Learn Hardcore Hungarian: A diák késő este tanul. - The student studies late in the evening.

Why do we use tanul in the indefinite conjugation here?

Since there’s no specific object being studied (for instance, we’re not saying A diák a könyvet tanulja), the action is indefinite: the student is studying something in general. In Hungarian, the indefinite conjugation is used if there isn't a definite, specified direct object.

What is the function of késő este in this sentence?

Késő este (literally “late evening”) is an adverbial phrase that indicates when the studying takes place. You can think of it as specifying the time of day, similar to “in the late evening” in English.

Can I say A diák tanul késő este instead?

Yes, you can. Hungarian word order is flexible, and placing the time expression at the end or after the subject are both natural. In a neutral sentence, either position sounds fine.

What’s the difference between using a and egy before diák?

Using a (“the”) indicates you’re talking about a specific student. If you said Egy diák késő este tanul, you’d be referring to a student (any student) instead of the student. Both are grammatically correct but convey slightly different meanings.
