The main point of the keyword phrase "September 11th art" is the word "art," which functions as a noun. In this construction, "September 11th" acts as a compound adjectival modifier, specifying the subject, theme, or origin of the art being discussed.
Grammatically, this is a noun phrase where "art" is the head noun, establishing the primary subject. The preceding term, "September 11th," is a proper noun that functions attributively to qualify the head noun. It answers the question, "What kind of art?" By modifying "art," it narrows the scope from the general concept of artistic creation to a specific category of works connected to the events of September 11, 2001. This structure is common in English for classifying objects or concepts by their context, origin, or subject matter (e.g., "Renaissance art," "war poetry").
Recognizing "art" as the central noun is crucial because it dictates that the article's primary focus must be on the artistic creations themselves. The analysis should center on the mediums, styles, themes, and aesthetic responses found within these works. The "September 11th" modifier provides the thematic lens through which the art is to be examined, but the core subject remains the analysis of the art objects and their cultural or historical significance as creative expressions.
