The success of the Indonesian nation to bring Malay language into a national language is a remarkable achievement that is not necessarily done by other nations.Many countries in the world, such as India, Philippines, Singapore, and so on have not succeeded in following the success of the Indonesian nation in establishing their language policy line. However, this success is not supported by the positive attitude of its speakers to maintain and develop its national language. In this regard, the pride of Indonesian and the pride of local languages as an element of Indonesian language and cultural development must be continuously improved. Keberhasilan bangsa Indonesia mengangkat bahasa Melayu menjadi bahasa nasional merupakan prestasi yang luar biasa yang belum tentu dapat dilakukan oleh bangsa lain. Banyak negara di dunia, seperti India, Filipina, Singapura, dan sebagainya sampai sekarang belum berhasil mengikuti kesuksesan bangsa Indonesia dalam menetapkan garis kebijakan kebahasaannya. Namun, keberhasilan ini ternyata tidak didukung oleh sikap positif para penuturnya untuk mempertahankan dan mengembangkan bahasa nasionalnya. Sehubungan dengan itu, kebanggaan terhadap bahasa Indonesia dan bahasa-bahasa daerah sebagai unsur pengembangan bahasa  dan budaya Indonesia harus terus ditingkatkan.
