What does teheran mean in farsi?

"Tehran" itself is not a Persian word with a direct translation. It's the name of the city, and it's believed to be derived from the Persian word "Tihran".

However, "Tihran" doesn't have a clear meaning in modern Persian. It might be related to:

* "Tih" (meaning "empty" or "void"): This suggests a historical connection to a place that was once barren.

* "Tiran" (meaning "tyrant"): This could refer to a historical figure or event associated with the city.

Ultimately, the exact meaning of "Tehran" is not certain. It's a historical name with possible etymological connections to Persian words, but its precise origin and meaning remain debated.
