It can be said that shortened nouns are one of the subtypes of nouns in the Arabic language, which end with the letter “yaa” and the last letter of these nouns is fixed, such as the words “world” and “al-la.” Shortened nouns are widely used in the Arabic language in forming nominal sentences, and they help convey the meaning accurately and clearly. In addition, speech in the Arabic language is divided into three main sections: the noun, the verb, and the letter. The noun plays an essential role in determining quantity and gender. Nouns can be divided into several other types, including incomplete nouns, abstract nouns, and relative nouns. Understanding these types enhances mastery of the Arabic language and ease of dealing with it.
