The keyword phrase "boston patriots day presidents" functions grammatically as a noun phrase. The main point and core part of speech for this phrase is the final word, the plural noun "presidents." The preceding words, "boston" and "patriots day," act as noun adjuncts (nouns used as adjectives) that modify and specify this primary noun.
In this construction, "presidents" serves as the head of the phrase, identifying the primary subject. The modifier "Patriots Day," itself a compound noun, narrows the focus to presidents in the context of that specific holiday. The initial modifier "Boston" further refines the scope to a geographical location intrinsically linked with the holiday's observance. This stacking of noun adjuncts creates a highly specific subject: presidents as they relate to Patriots' Day in Boston.
For the purpose of an article, this grammatical structure dictates that the central theme must be U.S. Presidents. The article's content should explore the intersection of these figures with the holiday and its Boston-centric context. Potential topics would include presidential actions, proclamations, visits, or historical ties (such as the connections of early presidents like John Adams to the Revolutionary War events commemorated) relevant to this specific holiday and location.
