What year did Farsi become a language?

Farsi, also known as Persian, doesn't have a specific "birth year" like a person does. Languages evolve over time, and Farsi is no exception.

Here's a breakdown:

* Ancient Roots: The roots of Farsi can be traced back to Old Persian, the language of the Achaemenid Empire (550-330 BCE).

* Middle Persian: Over time, Old Persian evolved into Middle Persian, which was spoken during the Sassanid Empire (224-651 CE).

* Modern Persian: The modern form of Farsi (also known as New Persian) emerged around the 9th century CE. This period saw the influence of Arabic and the development of a standardized literary form.

Therefore, it's more accurate to say that Farsi evolved over centuries, with the 9th century marking a significant transition towards the language we know today.
