The keyword phrase functions as a noun phrase. It is composed of a proper noun, "Patriots Day," which acts as a specifier, and an adjective, "Asian," which modifies an implied or elided noun. As the main point of an article, the entire term represents a specific topic, concept, or subject of inquiry.
Grammatically, the phrase is an elliptical construction. "Patriots Day" establishes the context, functioning like an adjectival noun that specifies the occasion. "Asian" is a descriptive adjective. The head nounthe core subject being describedis omitted but understood from the context of the intended article. This implied noun could be "person," "experience," "perspective," "community," or "event." For example, the full phrase could be interpreted as "the [Asian experience] of Patriots Day" or "[an Asian person's] Patriots Day."
For the purpose of structuring an article, treating the phrase as a noun phrase is essential. It establishes the central subject matter: the intersection of the holiday and individuals or groups identified as Asian. This allows the article's thesis to focus on a concrete subjecta specific group's relationship to a specific eventrather than an action (verb) or a quality (adjective). The article's content would then explore, define, or analyze this specific subject.
