Learn Farsi: تیراژ کتاب چهارم خیلی کم است. - The print run of the fourth book is very low.

In Farsi, ordinal numbers that end in -om (like چهارم) act like regular adjectives. They come after the noun they modify, and you must connect them using the Ezafe. So, you say کتابِ چهارم (ketab-e chaharom).

Is it possible to put "fourth" before "book" in this sentence?

Yes! If you want to put the ordinal number before the noun, you must add -in to the end of it, making it چهارمین (chaharomin). When used before the noun (as چهارمین کتاب), it sounds a bit more emphatic, and you do not use the Ezafe.

What exactly does تیراژ (tirazh) mean?

It means "print run" or "circulation"—meaning the number of copies of a book or newspaper printed at one time. It's a loanword from the French word "tirage," which is why it uses the ژ (zh) sound.

Why is کم (kam) translated as "low" here instead of "little"?

While کم usually translates to "little" or "few," in Farsi it is also the standard adjective used to describe numerical amounts, rates, or statistics as being "low." Because تیراژ represents a numerical quantity of books, we use کم to say that number is low.
