The keyword term functions as a noun phrase. The core of this phrase is the plural noun "events," which is modified by the preceding date, "september 11th 2001." In this grammatical construction, the date serves as an adjectival phrase, specifically a noun adjunct, that specifies the particular set of occurrences being referenced.
Analytically, "events" is the head of the phrase, establishing the subject matter as a series of actions or happenings. The modifier "september 11th 2001" pinpoints these actions to a singular, historically specific context. This structure allows the entire phrase to function as a unified grammatical unita subject, object, or complement within a sentence. Recognizing this is critical for writing because it ensures the article's focus remains consistently on the occurrences themselves, rather than treating the date and the happenings as separate concepts.
By defining the main point as a noun phrase, the article's central theme is firmly established as a substantive topic for analysis. The narrative and argumentative framework is thus built around the nature, causes, and repercussions of the occurrences. This grammatical choice is foundational, as it directs the entire discourse to explore the specific actions and their impact, providing a clear and concrete subject for historical and political examination.
