The keyword term functions as a noun phrase, with the word "stories" serving as the head noun. This identifies the core subject of the article as narratives or accounts. The words "september 11th" and "survivor" act as modifiers, specifying the nature and origin of these narratives.
A detailed grammatical analysis reveals the structure: "Stories" is the central noun. "Survivor" is a noun functioning as an attributive noun (or noun adjunct), which modifies "stories" by defining who the narratives belong to. The term "september 11th" is a proper noun that, in turn, modifies "survivor," specifying the particular event these individuals endured. The combination "september 11th survivor" acts as a compound modifier for the head noun "stories."
This grammatical structure dictates that the article's primary focus must be on the personal testimonials and recounted experiences of individuals. The central theme is not the event itself in a historical or political sense, but rather the human experience as communicated through firsthand accounts. The article's content should therefore consist of presenting, compiling, or analyzing these specific personal narratives.
