Did You Know That:

The existence of Iranian pronunciation for numbers two- دو (dough), five- پنج (panj), and six- شش (shesh) in Polish language, two- دوا (dwa), five- پینجِی (peeyenj) and six- ششج (sheshej) indicates a distant and common root of these two Indo-European languages.

Similarly, the given name Darius (داریوش) is more frequently used than in Iran and Marjan- مرجان (Mardjan) and other original Iranian given names are mostly common.
