One of the advantages of Ajip Rosidi as a writer of language columns in newspapers is his personal involvement in the history of the formation and development of Indonesian. He not only writes down the results of observations and concerns over the use of the national language today, but always complements his writings with historical arguments and debates that have occurred, so that the reader can easily understand the historical background of many contemporary linguistic issues. On the other hand, he placed the vernacular as equivalent, just as important, as the national language. He is not tired of inviting us to care for and preserve our mother tongue or regional language, because this is one of our cultural treasures as a nation.
