FOR Krishna Sobti ("70-plus," she whispers evasively), politics stems from language. "Can you imagine," she shudders, "the horror of the word adhyaksh mahoday? I would always use sahib-i-sadr. And what about that other abomination, padhariye? Awful. Krishna Tashreef rakhiye, on the other hand, is generous, lofty." She gestures grandly towards the snow peaks that surround the sudden Gothic beauty of the Indian Institute of Advanced Study (IIAS) in Shimla, where she is a national fellow.
