Rooted in religion and based on a division of labor, the caste system, among other things, dictates the type of occupations a person can pursue and the social interactions that she may have. Castes are an aspect of Hindu religion. Other religions in India do not follow this system.
The name Pakistan literally means land of the pure in Urdu and Persian. It is a play on the word pÄk meaning pure in Persian and Pashto; the suffix -stÄn is a Persian word meaning place of, cognate with the Sanskrit word sthÄna (Devanagari: à¤¸à¥à¤¥à¤¾à¤¨ [stÌªÊ°aËnÉ]).
What is the meaning of Pakistan? Pakistan means land of the clean. It does not mean land of the pure, as some Pakistanis might fool you into believing, because pak means clean in Urdu and stan means land in Farsi, the i between pak and stan means of in Farsi and Urdu. In the languages of Pakistan and Iran the predicate always comes before the subject.
