* "Middle East" is a broad term: Its geographical boundaries are debated, and the term can encompass a variety of cultures and languages.
* Farsi is spoken in multiple countries: While Farsi is the official language of Iran, it's also spoken in Afghanistan (as Dari) and Tajikistan.
* Other languages are spoken in the region: Arabic is the dominant language in many Middle Eastern countries, and there are numerous other languages and dialects.
To give you a general idea:
* Iran: The majority of Iran's population speaks Farsi.
* Afghanistan: Dari, a closely related language to Farsi, is spoken by a significant portion of the population.
* Tajikistan: Farsi is the official language, spoken by a majority.
Instead of a percentage, it's more accurate to say that Farsi is an important language in the Middle East, particularly in the eastern part of the region.
