Questions & Answers about بچهها در اتاق مطالعه میکنن تا تو برمیگردی.
Why does the verb میکنن end in ـن instead of ـند?
This is exactly what you are learning in this lesson! The formal written form is میکنند (mi-kon-and). In everyday colloquial Tehrani speech, the final 'd' sound in the 3rd-person plural ending is dropped. So, the formal -and becomes -an, and میکنند is spoken and informally written as میکنن.
Is مطالعه کردن the only way to say "to study" in Farsi?
No, and there is a helpful distinction. مطالعه کردن specifically means reading, reviewing texts, or doing research quietly (which makes sense since they are in a room). If you want to talk about studying a subject at school or university, you usually use درس خواندن (literally "to read lessons").
Why is the verb برمیگردی in the present indicative? Doesn't تا (until) usually require the subjunctive?
Great catch! Yes, تا meaning "until" is normally followed by the subjunctive (تا تو برگردی). However, using the present indicative (برمیگردی) here shifts the meaning slightly. Instead of a hypothetical "until you return", it translates closer to "by the time you get back" or "while you are on your way back", treating your return as a definite, ongoing action.
How does the prefix بر work in the verb برمیگردی?
The verb برگشتن (to return) is a prefix verb. Unlike typical compound verbs (like مطالعه کردن) where the two words stay separate, the prefix attaches directly to the verb. When conjugating in the present tense, the continuous prefix slips right between the prefix and the stem, resulting in (bar-mi-gardi).
