The keyword term functions as a noun phrase. The principal part of speech, which dictates its grammatical role and serves as the main point, is the noun "overview." This word acts as the head of the phrase, establishing the term's core identity as a subject or object within a sentence.
In this construction, "September 11th," which is a proper noun, operates as a noun adjunct. A noun adjunct is a noun that modifies another noun, functioning similarly to an adjective. It specifies the type or subject of the head noun. Therefore, "September 11th" is not the main point itself but a qualifier that defines the specific content of the "overview." The grammatical structure identifies the subject as a summary or general survey, specifically one concerning the events of September 11th.
Understanding this grammatical role is crucial for structuring an article around the term. Since the main point is "overview," the article's central purpose must be to provide a comprehensive, high-level summary of the topic. The focus should be on breadth rather than a deep-dive into a single, narrow aspect. The term directs the writer to synthesize information and present a general, coherent picture of the subject, fulfilling the expectation set by the head noun "overview."
