Making the wrong letter the correct letter course

Abstract

The research deals with the conversation about vowels, showing their weakness and that there is a lot of change and deletion in them unlike the correct letter, but in places of prose and poetry it has been treated as the correct letter and has taken its rule, as in the other ill-present tense and the derived nouns, and it has shown that the ill letter that treats the correct treatment is located in The end of the word, and it may be in the middle of it, and I was keen in the search to clarify and limit those places, and that was in the first topic. As for the second topic, it was about the position of the grammarians regarding the conduct of the defective letter in the correct course, some of them considered that a language for some Arabs, and some of them denied this language and made what was mentioned of this kind a matter of poetic necessity, such as Al-Khalil and Sibawayh, and others went to the interpretation of that in another way that keeps the letter The reason is based on its status and does not follow the correct course, and some grammarians, such as Ibn Malik and Ibn Hisham, believe that this is a diseased procedure that follows the correct course.
