The call to rethink the ban on dialects elicited a swift reply from Minister Mentor, Lee Kuan Yew. “I thought it was a daft call. My then-principal private secretary Chee Hong Tat issued a reply on my behalf: Using one language more frequently means less time for other languages. Hence, the more languages a person learns, the greater the difficulties of retaining them at a high level of fluency… It would be stupid for any Singapore agency or NTU to advocate the learning of dialects, which must be at the expense of English and Mandarin.’
