The keyword term functions as a noun phrase. The core part of speech, and the main point for an article, is the noun "review." The proper noun "Patriot Day" acts as a noun adjunct, modifying "review" to specify its subject matter.
In this grammatical construction, "Patriot Day" qualifies the head noun "review," indicating that the content is an analysis, critique, or retrospective examination of a subject related to that day. This subject could be the 2016 film Patriots Day, a specific commemorative event, or the cultural significance of the observance itself. The phrase refers to a specific piece of work (the review) rather than an action (the verb 'to review').
Understanding this structure is crucial for content strategy. The article's primary purpose should be evaluative and analytical, consistent with the definition of a review. The content must go beyond simple description to offer a critical assessment, interpretation, or judgment on the chosen subject, thereby fulfilling the user's expectation for a piece of critical commentary.
