The term "patriots day boston film" functions grammatically as a noun phrase. In this construction, the word "film" serves as the head noun, which is the core subject. The preceding words, "patriots day" and "boston," act as noun adjuncts (or attributive nouns). They function like adjectives to modify and specify the type of film being discussed.
A detailed analysis reveals a hierarchy of modification. The noun "boston" modifies "film" to create the compound idea of a "boston film," specifying its geographical setting or focus. Subsequently, the proper noun "patriots day" modifies the entire unit "boston film," specifying its subject matter. This sequential modification creates a highly specific nominal concept. Unlike true adjectives, these noun adjuncts are not typically gradable (e.g., one cannot say "more patriots day"). Their purpose is classification rather than description, defining the film by its key identifiers: subject, location, and medium.
For the purpose of an article, establishing this phrase as a noun phrase is critical because it defines the subject as a singular, concrete entity: a specific cinematic work. This determination dictates that the article's focus should be on the analysis, review, or discussion of this particular movie. The grammatical structure signals that the holiday and the city are not the primary subjects themselves, but rather essential classifiers for the main subject, which is the film.
