The keyword phrase "911 lone star season 3" functions grammatically as a proper noun. It serves as a specific name for a unique entity: the third season of the television series titled 9-1-1: Lone Star. As a proper noun, it acts as the primary subject or topic of the article, rather than as a descriptor (adjective) or an action (verb).
This classification is based on its construction. The core component, "9-1-1: Lone Star," is the official title of the media property, which is a proper noun. The subsequent terms, "season 3," act as a specific identifier that modifies this title. In grammatical analysis, when a common noun like "season" is combined with a specific number and appended to a title, the entire phrase operates as a single, compound proper noun. It is treated as a singular unit that names a particular installment of a creative work, similar to titles like "Star Wars: Episode IV" or "Harry Potter and the Chamber of Secrets."
Identifying the phrase as a proper noun is the crucial first step because it establishes the article's main point and subject matter. This determination dictates that the article's content will focus on the specific events, characters, production, and reception of this particular season. For stylistic and SEO purposes, this means the phrase refers to a concrete topic and should be treated as the central subject around which all related information is structured.
