The keyword phrase "Patriots Day 2025 US" functions as a proper noun phrase. Its primary grammatical role is to name a specific, unique event: the observance of the holiday Patriots Day in the United States during the year 2025.
This phrase is constructed from a core proper noun, "Patriots Day," which is modified by two other elements. "2025" is a numerical adjective specifying the year. "US" (an abbreviation for United States) is a noun used as an adjective (a noun adjunct) to specify the geographical location. Together, these components do not describe an action (verb) or a quality (adjective/adverb) but rather identify a singular, specific subject.
Understanding this classification is crucial because it establishes the keyword as the central subject of the article. As a proper noun phrase, it will typically function as the subject or object within sentences, directly defining the topic. This dictates that the article's content should provide specific informationsuch as the date, historical context, and eventsrelated to this particular holiday observance, rather than discussing general concepts.
