Kurdish is a member of the Western Iranian branch of Indo-European languages. Approximately 16 million people speak Kurdish in Iraq, Turkey, Iran, Syria, Lebanon, Armenia, Georgia, Kyrgyzstan, Azerbaijan, Kazakstan and Afghanistan
In Turkey Kurdish is written with the Latin alphabet and in parts of the former Soviet Union it is written with the Cyrillic alphabet.
When Kurdish is written with the Arabic script, Arabic loan words retain their original spelling, though are often pronounced quite differently in Kurdish.
