The keyword term "patriots day jersey red sox" functions as a noun phrase. In this construction, the word "jersey" is the head noun, or the central subject. The terms "Patriots' Day" and "Red Sox" act as adjectival modifiers that specify and describe the noun.
Grammatically, the phrase is a compound of multiple nouns where some serve an attributive function. "Patriots' Day," a proper noun for a civic holiday, and "Red Sox," a proper noun for a sports team, both modify "jersey." This structure creates a highly specific identifier for a particular object. The phrase does not describe an action (verb) or qualify another word (adverb), but rather names a distinct, tangible item.
Understanding this phrase as a noun phrase is critical because it defines the article's subject as a specific piece of apparel. The focus is not the holiday, the team in general, or jerseys broadly, but the singular, concrete item that exists at the intersection of these three concepts: the uniform worn by the Boston baseball team to commemorate the specific holiday.
