The keyword term "september 11th due date" functions grammatically as a noun phrase. A noun phrase is a group of words that serves the same purpose as a single noun, identifying a specific person, place, thing, or concept.

The core of this phrase is the compound noun "due date," where "date" is the head noun and "due" is an adjective modifying it.

The article's purpose is to define, explain, or analyze this specific deadline as a central topic.
