It is the specific, capitalized name assigned to a singular historical event, much like "World War II" or "the Great Depression."
As a proper noun, "September 11th" (or its numeronym, "9/11") is elevated from a simple calendar date to the title of a complex event. This grammatical classification allows the term to act as the subject or object in a sentence, enabling direct analysis of its causes, effects, and legacy. For example, in the statement "September 11th changed global air travel," the phrase serves as the subject performing the action. This is distinct from its function as an adverbial phrase of time, such as in "The policy was enacted on September 11th, 2002." The capitalization and context are key indicators of its function as the name of the event.
Understanding this term as a proper noun is fundamentally important for an article because it establishes the event itself as the central subject of inquiry. This allows the article to be structured around defining, analyzing, and interpreting "September 11th" as a singular entity. Your main points, arguments, and evidence can then directly relate to this core subject, providing a clear and focused analytical framework for discussing its historical, political, or social significance.
