The keyword term "patriots day holiday ma" functions as a noun phrase. In this construction, "holiday" is the head noun, which is modified by the proper noun "Patriots' Day" and the proper noun abbreviation "MA" (Massachusetts). The entire phrase serves to name a specific entity: a particular legal observance in a specific U.S. state.
Grammatically, both "Patriots' Day" and "MA" act as noun adjuncts, which are nouns that modify other nouns, functioning like adjectives. "Patriots' Day" specifies the name of the holiday, and "MA" specifies its geographic location. This syntactic structure distinguishes the subject as a concrete concept or event, rather than an action (verb) or a descriptive quality (adjective). The phrase's composition provides three layers of specificity: the category of the thing (holiday), its official name (Patriots' Day), and its jurisdiction (MA).
This grammatical determination is crucial for developing an article around the keyword. Because the subject is a noun phrase identifying a specific event, the article's primary purpose should be informational and descriptive. The content should focus on defining the holiday, explaining its historical context (e.g., the Battles of Lexington and Concord), detailing its modern observances (e.g., the Boston Marathon), and clarifying its status as an official holiday in Massachusetts. The part of speech dictates that the article's focus is on the "what, where, and why" of the event itself.
