Challenging Indo-European Theory of Languages Dr. Manzur Ejaz (Author) This book evaluates the relevance of theory of Indo-European languages to non-Dravidian Indian languages. Linguistic and historical data reveals that this theory does not hold. Neither non-Dravidian languages are polluted forms of Sanskrit nor European languages of vulgar Latin. Furthermore, it is shown that non-Dravidian Indian languages are based on the speech of Harappa Civilization. Sanskrit, being the language of pastoral tribal people, had to borrow heavily from indigenous languages creating a misplaced perception of being the mother of many languages. Linguistic and historical data is employed to show that neither Dravidian nor Sanskrit is the source of most of Indian languages. The conclusions drawn lead us to reformulate the entire linguistic theory for non-Dravidian languages of the subcontinent.
