Persian language
The Iranians were one branch of the Indo-European family of peoples who moved out of what are today the Russian steppes to settle in Europe, Iran, Central Asia, and northern India, in a series of migrations and invasions in the latter part of the second millennium bc. This explains the close relationship between the Persian language and other Indo-European languages— particularly Sanskrit and Latin, but also modern languages like Hindi, German, and English. Any speaker of a European language who is learning Persian soon encounters a series of familiar words: pedar (father, Latin pater); dokhtar (daughter, girl, German tochter); mordan (to die, Latin mortuus, French mourir, le mort); nam (name); dar (door); and perhaps the most familiar of all, the first-person present and singular of the verb to be, the suffix—am (I am—as in the sentence “I am an Iranian”—Irani-am). An English-speaker who has attempted to learn German will find Persian grammar both familiar and blessedly simple by comparison. There are no genders or grammatical cases for nouns. Persian, like English, has evolved since ancient times into a simplified form, dropping the heavily inflected grammar of old Persian. It has no structural relationship with Arabic or the other Semitic languages of the ancient Middle East (though it took in many Arab words after the Arab conquest).
