Learn Farsi: کفاش همانی است که کفش سفارشی را می‌دوزد. - The cobbler is the very one who sews the bespoke shoe.

The word همان (that same) gets the restrictive suffix ی (-i) to act as a standalone pronoun meaning "the very one" or "that exact person/thing". The که (who/that) then introduces the relative clause that describes them. Together, همانی که translates cleanly to "the very one who".

Why is the verb است in the middle of the sentence instead of at the very end?

While the main verb in Farsi usually goes at the absolute end, relative clauses starting with که are an exception. To avoid trapping the simple verb است (is) behind a long descriptive clause, Farsi places it right after the head noun/pronoun (همانی). This keeps the main clause "The cobbler is the very one" intact before launching into the "who..." part.

Does Farsi really use the verb "to sew" (دوختن) for making shoes?

Yes! The verb دوختن (to sew) is traditionally used for cobblers making or repairing shoes (کفش دوختن), since crafting leather footwear heavily relies on stitching. The present stem is دوز (duz), giving us می‌دوزد (he/she sews).

Is the ی at the end of سفارشی the same grammar rule as the one on همانی?
