The keyword term "patriots day the movie" functions as a proper noun. It acts as a single grammatical unit to name a specific entity: the 2016 film titled Patriots Day. This classification is the main point because it dictates how the term is treated grammatically within any sentence or context.
Grammatically, the term is a noun phrase, where "movie" is the head noun. The words "Patriots Day" act as a noun adjunct or modifier, specifying which movie is being referenced. Although "Patriots Day" is itself a proper noun (referring to the holiday), in this construction, it functions adjectivally to distinguish this film from any other. The entire phrase collectively serves the function of a proper noun, similar to how "The Lord of the Rings" or "New York City" are treated as single, specific names.
Recognizing the term as a proper noun is crucial for the article's clarity and grammatical correctness. It ensures the phrase is treated as a singular subject (e.g., "Patriots Day the movie is an action-thriller..."), is capitalized correctly as a title, and is understood by the reader as a reference to one specific work, not a general discussion about a movie related to the holiday. This grammatical foundation prevents ambiguity and maintains a professional tone.
