Learn Farsi: نقاش هنوز سقف را رنگ نکرده است، چون خیس است. - The painter has not painted the ceiling yet, because it is wet.

The verb for "to paint" is made of two parts: the noun رنگ and the verb کردن. To make it negative present perfect, we only change the second part. We add the negative prefix نـ to the past participle کرده, and follow it with the short "to be" verb است. Together, this makes رنگ نکرده است.

How does the word هنوز work with the negative verb in this sentence?

هنوز typically means "still." However, when you use it in a negative sentence like this one alongside نکرده است, it translates to "yet" or "not yet."

Why is the direct object marker را used after سقف?

را tells us that the direct object is specific and definite. The painter isn't just painting any random ceiling; he is painting "the" specific ceiling. Because of this, we put را right after سقف to show it is the specific target of the action.

The translation says "because it is wet," but where is the Farsi word for "it"?

Farsi frequently drops subject pronouns when the meaning is clear from the situation. The phrase چون خیس است literally translates to "because is wet," and we naturally understand that the missing subject is the ceiling.
