zaruun : west
The Tarijan word for west is zaruun.
Similarly named Zarun is the name of a town in Iran.
How I came up with this word:
Zaruun is a mixture of the transliterated word for west in Russian which is zapad (запад), and the transliterated word for west in Mongolian which is baruun (баруун).
There is another Mongolian word for west, örnöd (өрнөд).
