Many books have recently been written to correct the general mistakes. In the modern age, there has been a tendency to activate the linguistic correction for which supporters were from different cultures and different references as well. Thos has led to to create a variation in both style of research writing and conduction. Although the old linguists had their own interest in reforming language and dealing with mistakes , the modern age linguists were known by many students as well as scientists who had their active contributions in this field, such as the Father Anstas Mary Al- Keremly ,Prof. Kamal Ibrahim , Dr. Mustafa Jawad, and. Asa’d Khalil Daghir ,Dr. Ibrahim Al-Samaraey ,Al-Sheikh Ibrahim Al- Yaziji and. Ibrahim Al- Wa’ely and Dr. Nima Raheem Al-Azawy. Critics have been divided into three groups: the first was known with severity in accepting evolution; the second group of modern critics have made their own way of tolerance satisfying the old critics; while the third and smaller group included a small group of scientists who mixed both of the styles: the normative severity in some works and the descriptive lenient direction. The modern linguistic criticism included the mistakes in morphology, syntax, linguistics and spelling; while the phonological linguistic criticism was concerned with replacing of letters or changing the vowel sounds.
