Learn Farsi: تمام کتاب‌ها اینجا است.

To make a noun plural in Farsi, you just add -hā (ها) to the end of the word. Here, ketāb (book) becomes ketāb-hā (books). This is the most common and regular way to make plurals, similar to adding "-s" in English.

Why is there a tiny gap between ketāb (کتاب) and hā (ها) in کتاب‌ها?

In modern Farsi typing, we often use a "half-space" before suffixes like -hā. This keeps the original word's shape intact. If it were typed with a regular connection, the letters would join together as کتابها. Both spellings are perfectly correct and common, but the half-space makes recognizing the root word easier for beginners.

Why does the sentence end with ast (is) instead of a plural verb for "are"?

This is a very important rule in Farsi! When the subject of a sentence is plural but inanimate (not a living human or animal, like books), the verb is usually singular. So, saying "the books is here" (ketāb-hā injā ast) is the natural and grammatically correct way to say "the books are here" in Farsi.

How do the words tamām (all) and ketāb-hā (books) connect when speaking?

They are connected by a hidden "e" sound, known as the ezafe. Even though it is not written in the Farsi alphabet here, you pronounce the phrase as tamām-e ketāb-hā. This little spoken vowel links a quantity or describing word to the noun that follows it.
