Prime Minister Narendra Modi on Friday vouched for the use of mother tongue as the medium of instruction in schools. Speaking at an event organised by the Education Ministry, the prime minister said that “people trapped in bookish knowledge” often fail to grasp that language is a way to communicate knowledge and not the entire knowledge in itself. The PM also made it clear that while local languages were being promoted in the new National Education Policy, there was no bar at all on the teaching of English or any other language that can be helpful on the global stage.
