Learn Farsi: گذرنامه باطل نشده بود. - The passport had not become invalid.

It uses the negative prefix na- attached to shode (the past participle of shodan, meaning to become), followed by bud (the simple past of budan, meaning to be, in the third-person singular form). This combination gives us "had not become."

Why do we use a form of shodan instead of kardan with the word bātel?

bātel shodan is a compound verb meaning "to become invalid" or "to expire." If a specific person had actively canceled the passport, you would use a form of kardan (to do/make). Here, the passport is the subject simply holding a state, so we use shodan.

What does the -nāme part of gozārnāme mean?

The suffix -nāme means "document," "record," or "letter" in Farsi. Combined with a root word related to passing or crossing, it creates the word for "passport." You likely already know this suffix from ruznāme (newspaper) or kārnāme (report card).

The word bātel is spelled with the letter ط. Does this change its pronunciation?

No, in Farsi the letter ط sounds exactly the same as the standard letter ت (te). It is used here because bātel is an Arabic loanword, and Farsi keeps the original Arabic spelling even though the pronunciation is simplified.
