Learn Farsi: چرا کوله‌پشتی رو داخل ترمینال جا گذاشتی؟ - Why did you leave the backpack inside the terminal?

In colloquial Tehrani Farsi, the written object marker را changes depending on the last sound of the word before it. It becomes رو after words ending in a vowel, and it shrinks to just و (pronounced "o") after consonants. Because کوله‌پشتی ends in the vowel sound "i", it takes رو.

What exactly does the verb جا گذاشتی mean literally?

It comes from the compound verb جا گذاشتن, which literally translates to "to put a place" (جا means place, and گذاشتن means to put). In Farsi, this combination is the standard way to say you accidentally left something somewhere or forgot it behind.

Is there a hidden linking vowel (ezāfe) between داخل and ترمینال?

Yes, you must pronounce it as داخلِ ترمینال (dākhel-e termināl). The word داخل acts as a preposition here (meaning "inside of"), so it requires the ezāfe to connect it to the noun it refers to, which is ترمینال.

Why is the location (داخل ترمینال) placed after the backpack but before the verb?

Farsi verbs almost always sit at the very end of the sentence. Because the backpack is a specific direct object marked by رو, it is placed relatively early in the sentence. Prepositional phrases showing location, like داخل ترمینال, naturally slot into the space between that specific object and the final verb.
