The keyword term functions as a compound noun or noun phrase. In this grammatical structure, "remembrance" serves as the head noun, identifying the core subject as an act of commemoration. The preceding element, "sep 11," operates as a noun adjunct, modifying the head noun to specify its particular focus.
A detailed analysis of the phrase breaks it into two components. The primary element is "remembrance," a noun that denotes the act of remembering or a memorial. The secondary element is "sep 11," a proper noun referring to the specific date of the 2001 terrorist attacks. In this context, "sep 11" is used attributively, meaning it functions like an adjective to qualify the noun that follows. It answers the question, "What kind of remembrance?" The combination forms a single lexical unit representing a specific, culturally significant event of commemoration.
Understanding this phrase as a unified noun concept is essential for writing the article. It allows the term to function as a clear and consistent subject or object within sentences (e.g., "The [phrase] is observed annually," or "The nation participates in the [phrase]"). This grammatical classification ensures the article's focus remains on the specific commemorative event, rather than diffusing into separate discussions of the date and the general concept of memory, thereby maintaining thematic integrity and clarity.
