Some words. I believe. I just found out that Fasi is the universal language among Indians until the British took over India. Is that true?
No, not really. Farsi was used in parts of the Mughal government because the Mughals themselves were of Persianate origin, but the common people of India never spoke Farsi. However, the modern-day languages of Hindi and Urdu have borrowed some words from Farsi.
Also, it should be noted that the world copied much more from India than India ever copied from the world. Just a few things include:
The modern numeral system, the concept of zero, chess, the basic cotton gin, chintz fabric, advanced steelworking techniques (crucible and wootz steel), dikes and advanced irrigation techniques, dental drills, plastic surgery, dyes, furnaces, ink, muslin fabric, pajamas, rocket artillery, radio, measuring implements (rulers), globes, toe stirrups, wool, the cultivation of sugarcane and cotton, algebra and trigonometry, Pascal's triangle (several thousand years before Pascal), basic calculus, inoculation, and sewers.
The Persians invented many things as well. So did the Chinese, and the Romans. I think those four civilizations are responsible for most of the world's progress since the human race began.
