The keyword term "911 x reader" functions grammatically as a compound proper noun. It operates as a single, indivisible unit that names a specific subgenre of fanfiction. The phrase designates narrative works where a character from the television series 9-1-1 is paired romantically or relationally with a character representing the audience ("the reader").
This classification is based on its function within discourse and digital archives. The entire phrase acts as a label or title for a distinct category of creative work. While its components can be analyzed separately (a proper noun "911," a conjunction or symbol "x," and a common noun "reader"), they combine to form a singular semantic concept. The term can also function as a compound modifier when it precedes another noun, as in the phrase "a 911 x reader story," where it adjectivally describes the type of story.
For the purpose of analysis, treating the term as a proper noun is the most practical and accurate interpretation. This classification recognizes the phrase not as a simple description but as the specific name of a cultural artifact and literary category. This allows for a clear and consistent discussion of the subgenre's unique conventions, tropes, and audience engagement as a cohesive subject.
