The keyword term "september 11 new york" functions grammatically as a proper noun or a noun phrase. It operates as a single conceptual unit that names a specific, singular historical event. The individual words combine to create a distinct identifier, similar to other event-based proper nouns like "the French Revolution" or "World War II."
This classification arises from the combination of two proper nouns: "September 11," which denotes a specific date, and "New York," which denotes a specific location. When used together in this context, they form a compound proper noun that transcends its component parts to signify the series of terrorist attacks that occurred at that time and place. While the phrase can also function attributively (as an adjective) to modify another noun, as in "the September 11 New York recovery efforts," its primary grammatical role when standing as a keyword is that of a noun, representing the subject itself.
Recognizing the term as a noun is crucial for structuring an article because it establishes the event as the central subject or entity to be analyzed. This allows the writer to treat the topic as a concrete and distinct field of inquiry, ensuring that all subsequent information, analysis, and discussion directly relate back to this core subject. It provides a stable grammatical foundation for building clear, focused sentences and paragraphs about the event's causes, impacts, and legacy.
