The keyword term "patriots day boston movie" functions grammatically as a noun phrase. In this construction, the word "movie" serves as the head noun, which is the core subject. The preceding proper nouns, "Patriots Day" and "Boston," act as noun adjuncts (or attributive nouns), modifying the head noun to create a highly specific identifier for a particular cinematic work.
A detailed grammatical breakdown reveals a hierarchy of modification. The primary noun is "movie." The proper noun "Boston" modifies "movie" to specify its geographical setting or context, narrowing the category to "Boston movie." The compound proper noun "Patriots Day" further modifies this unit, specifying the film's title or subject matter. This sequential use of nouns as modifiers is a common linguistic device for achieving precision, transforming a general category (movie) into a unique, singular entity.
The crucial implication of this analysis is that the article's main point must center on a specific, tangible entity. Because the keyword's grammatical function is to name a thing, the article should focus on describing, defining, or analyzing that particular film. The subject is not an abstract concept, an action, or a quality, but a concrete work, dictating an expository approach centered on the film itself.
