Are there exceptions to this rule? Are all nouns pluralized in this way? What is the condition of this plural of names? What are the conditions of this plural of adjectives? What are added to adjectives? There are three types of plurals: sound masculine plurals, sound feminine plurals, and broken plurals.
The general rule regarding sound masculine plurals is that its single form is not changed and a wāw and nūn with a fathah is added to the end of the word when it is in the nominative case and a yā' and nūn with a fathah is added to the end of the word when it is in the accusative or genitive cases. For example: مُرسَلون َ و مُرسَلینَ.
The only nouns that are pluralized in this form are masculine proper nouns with intellects and their characteristics. The condition for names is that they do not have the feminine tā' and are not compound names, for example: سَعیدونَ.
