The keyword phrase is composed of two distinct parts of speech. "Patriot Day" is a proper noun, which functions as the central subject. The word "about" is a preposition, indicating the topic or subject matter of discussion. Therefore, the main point of any article using this term is the proper noun itself, not the entire phrase as a single grammatical unit.
In analyzing the structure, the proper noun "Patriot Day" serves as the core concept or entity. The preposition "about" signals an intent to seek or provide information concerning that noun. This combination is characteristic of a search query, where a user specifies a subject ("Patriot Day") and the nature of their interest ("about" it). The analytical step is to deconstruct this query to identify the primary subject, which is the noun. The preposition is a functional word that frames the user's informational need but is not part of the subject's name or a descriptor of it.
For practical application in writing, the article's focus must be on the proper noun. The content should be developed to provide information about Patriot Dayits history, significance, observances, and meaning. The main point is not the grammar of the search term but the subject it identifies. The article's thesis and structure should be built around defining and explaining the event designated by the proper noun, thereby directly addressing the informational intent signaled by the preposition.
