The process of civilization change affected the Turkish society's language profoundly and permanently, since it remains in between Islamic civilization and Western civilization. During the westernization process, rather than the words that are introduced to our language, evaluation of Arabic and Farsi words within the scope of simplification/nativisation, brought an eliminiation process under the guise of nativisation. Between 1967 and 1970, works of the people evaluating the nativisation under the name of "Pure Turkish" within the frame of "revolution" and the people claiming that they are serving to the "national language" by defending the "living Turkish" are evaluated. “Pure Turkish” advocates claimed that they saved Turkish from the influence of foreign languages while producing words without recognizing any rules. The mistake in this situation: Attempts to replace Arabic and Persian words used in Ottoman Turkish with French, Latin or English, can be seen. It is also noteworthy that trying to save Turkish from the influence of a foreign language and putting it under the yoke of another foreign language was presented as “purification." As in this contrast, many remarkable expressions have been described and presented under various titles. In the research, the subject of “Academy” was also examined. The idea of thought in the Language Academy was explained before the Turkish Language Institution was influenced by political changes and power, and originated from too much ideological behavior. The people who advocates the language simplification efforts by expert academics, writers and linguists rather than politicians and how they continue their efforts for the establishment of an academy are examined and evaluated. The question of language, which must be kept apart from political-ideological actions and discourses, should be considered only in the scientific view of experts in the field of language. Target; without moderation, without affecting the natural course of the language, without damaging our culture, to make changes and innovations, and It must be to leave a rich language with high expression power for next generation by developing Turkısh language.
