كيف و اخواتها في النحو العربي

The Arabic grammatical system includes a number of the tools that are used for different purposes and by different styles, hence there are different analysis and different significances. This paper attempts to study these nouns and tools that are commonly used as interrogative tools while they have more than one significance within the linguistic context. These significance had been collected in this independent research under the title( Kaifa wa Akhawatuha), where they are exhibited and shown orderly and in detail because they were scattered within different books. By this way, their uses, purposes and analysis became known, depending on what the ancient and modern grammarians had said , with grammatical examples of the Arab speech with the Qur'anic use of these tools. So, those who are interested on studying the Arabic language can realize them and recognizing their connection so that they would be able to understand and comprehend them.
