The keyword phrase functions grammatically as a noun phrase. The core part of speech, which serves as the main point, is the head noun "film." The preceding words, "Patriot Day" and "Boston," act as adjectival modifiers that specify the particular cinematic work being referenced.
In this construction, "Patriot Day," a proper noun serving as the film's title, and "Boston," a proper noun indicating the subject's location, both function as attributive nouns. They modify the head noun by providing specific, identifying characteristics. This grammatical structure, where nouns modify another noun, creates a highly specific compound term that pinpoints a singular entity within the broader category of "film."
This determination is crucial as it establishes the article's subject as a single, concrete entity: the specific movie about the Boston Marathon bombing titled Patriots Day. Understanding the phrase as a noun phrase dictates that the article's content must center on this specific filmits production, narrative, themes, and critical receptionrather than treating the constituent words as separate or abstract topics. The phrase operates as a single unit of meaning, defining the precise focus for all subsequent content.
