In Arabic Grammar, Nominal and Verbal Sentences Theory plays a crucial role in understanding the structure and syntax of the language. It classifies sentences into two categories: nominal and verbal.

Nominal sentences, also known as ismī sentences, focus on the subject or noun. These sentences do not have a verb but instead contain a noun or pronoun to express a complete thought. The noun is then followed by other elements such as adjectives or prepositions to provide more information. For example, “الطالب جميل” (The student is beautiful) is a nominal sentence where “الطالب” (the student) is the subject and “جميل” (beautiful) is the attribute.

On the other hand, verbal sentences, or fe’lī sentences, focus on the action or verb. They follow a similar structure to English sentences, where a verb is accompanied by a subject. Verbal sentences can be in different tenses, moods, and voices to indicate various aspects of the action. For example, “الطالب يدرس” (The student is studying) is a verbal sentence.

Understanding the concepts of Nominal and Verbal Sentences Theory is essential in mastering Arabic grammar and syntax, enabling learners to form coherent and grammatically accurate sentences.
