Learn Farsi: من وقت خوابیدن ندارم.

In Farsi, the infinitive (words ending in -dan or -tan) often acts like a verbal noun. Just like we might say "the act of sleeping" in English, Farsi uses the infinitive خوابیدن (khābidan) as a noun. It isn't conjugated because it isn't the main action of the sentence—the main verb is ندارم (nadāram, I do not have).

Is there an Ezāfe linking وقت and خوابیدن?

Yes! When spoken, it is pronounced vaght-e khābidan. Since the infinitive خوابیدن acts as a noun here, the Ezāfe (the short "e" sound) is required to link the noun وقت (vaght, time) to it. It literally translates to "time of sleeping".

Based on this lesson, how do I extract the present stem of خوابیدن?

First, you drop the -an from the infinitive to get the past stem, which is خوابید (khābid). Present stems can sometimes be irregular and require memorization, but for many verbs ending in -idan like this one, you simply drop the -id from the past stem. This gives you the present stem خواب (khāb).

How does ندارم become negative?

The affirmative verb is دارم (dāram, I have). To make it negative, you attach the negative prefix () directly to the front of the verb, giving you (, I do not have). Because Farsi sentences follow a Subject-Object-Verb order, this main verb sits at the very end of the sentence.
