The keyword term "film 11 sep" functions as a compound noun or a noun phrase. In this grammatical construction, "film" is the head noun, establishing the primary subject as a cinematic work. The subsequent term "11 sep," an abbreviation for the date September 11th, serves as a postpositive modifier or noun adjunct that specifies the subject matter of the film.
The function of "11 sep" is to qualify and narrow the general category of "film" to a specific subgenre: works that depict, are inspired by, or analyze the events of September 11, 2001. This structure acts as a concise, searchable label for a distinct body of media. While a verb-object interpretation (an imperative command "to film the event of 11 sep") is technically possible, its context as a keyword for an article makes the noun phrase interpretation the only logical one, as it refers to a category of existing artifacts for analysis rather than an action to be performed.
Determining the term's function as a noun phrase is crucial as it frames the article's analytical approach. This interpretation establishes the subject not as an action but as a collection of cultural products. Consequently, the article's focus is directed toward examining the themes, narrative structures, historical representation, and societal impact of these specific films. The keyword thereby defines a field of study, treating "film 11 sep" as a distinct genre or body of work subject to critical inquiry.
