The keyword term "patriots day boston holiday" functions grammatically as a noun phrase. In this construction, the group of words acts as a single syntactic unit to name a specific entity or concept. The core part of speech, which dictates its role in a sentence, is a noun. This phrase would serve as the subject, object, or complement, identifying the specific event that the article will describe.
A detailed analysis of the phrase reveals a layered structure of nouns and modifiers. "Patriots Day" is a proper noun, naming a specific holiday. "Boston" is also a proper noun, but here it functions as a noun adjunct (a noun used as an adjective) to modify "holiday," specifying the location. "Holiday" is a common noun that categorizes the event. Together, they form a compound noun structure where each preceding word adds a layer of specificity to the final noun, "holiday." The entire phrase collectively identifies one unique concept: the observance of Patriots' Day as a holiday in Boston.
Understanding this grammatical function is crucial for structuring the article. By identifying the keyword as a noun phrase, the article's main point becomes the definition, description, and exploration of this specific event. The content should focus on answering questions about this "thing": what it is, when it occurs, its history, and its significance. This contrasts with a keyword centered on a verb (which would require an article about an action) or an adjective (which would describe a quality). Therefore, the article's thesis and supporting paragraphs must be built around explaining this central noun concept.
