Following the recent Supreme Court verdict that mother tongue is not compulsory for primary education, the Utkal Sammilani here on Thursday stated that mother tongues would vanish from the country and Odisha, which was formed as a separate State on linguistic basis, would be the worst sufferer. Sammilani Mancehswar Industrial branch president Dillip Dashsharma said, “The longevity of a language depends on its use.If children don’t use their mother tongue then the languages will disappear gradually and the publication of books and newspapers in regional languages will be minimised.”
