A Sanskrit grammatical problem which has perplexed scholars since the 5th Century BC has been solved by a University of Cambridge PhD student.
Rishi Rajpopat, 27, decoded a rule taught by Panini, a master of the ancient Sanskrit language who lived around 2,500 years ago.
Sanskrit is only spoken in India by an estimated 25,000 people out of a population of more than one billion, the university said.
Mr Rajpopat said he had “a eureka moment in Cambridge” after spending nine months “getting nowhere”.
“I closed the books for a month and just enjoyed the summer – swimming, cycling, cooking, praying and meditating,” he said.
