Yasin

The keyword "Yasin" functions grammatically as a proper noun. This classification is consistent across its primary uses and is fundamental to how it should be treated within an article.

As a proper noun, "Yasin" refers to a specific, unique entity. Its two most prominent uses are: 1) as the title of the 36th chapter (srah) of the Qur'an, Srat Y Sn, and 2) as a common male given name in many Muslim-majority countries. In both contexts, it names a particular item or person, which is the definitive function of a proper noun. Unlike common nouns that refer to a general class of entities (e.g., "chapter," "person"), "Yasin" designates a specific one and is therefore capitalized in English.

For the purpose of your article, treating "Yasin" as a proper noun establishes that the subject matter is a specific entity. The article's main point should therefore focus on the attributes, significance, history, or interpretation of either the Qur'anic chapter or an individual with that name. The grammatical role dictates that the article will be an exploration of a specific subject, not a general concept, action (verb), or quality (adjective).
