The keyword phrase "911 ellise" functions grammatically as a proper noun. This classification is based on its role as a unique name or designator for a specific event, case, or individual. It combines a generic service identifier ("911") with a specific name ("ellise") to create a singular, identifiable reference, distinguishing it from all other instances.
The term is a compound construction. The element "911" acts as an adjectival modifier or part of a compound name, specifying the context as an emergency services call. The element "ellise," a proper name, serves as the unique identifier within that context. This structure is common in official documentation, legal proceedings, and media reporting to label specific incidents (e.g., "Case 7B," "Operation Desert Storm"). The primary purpose of such a construction is to create an unambiguous and standardized reference for a particular set of circumstances for purposes of record-keeping, analysis, and discussion.
Recognizing the phrase as a proper noun is the critical analytical step because it frames the subject matter as a specific case study. The focus is therefore not on the 911 system in general, but on the distinct facts, timeline, and individuals involved in the incident uniquely identified by this name. This determination directs the article's scope toward a detailed examination of a particular event, rather than a broad or theoretical exploration.
