The keyword term functions as a noun phrase. In this construction, the word "game" serves as the head noun, which is the central element of the phrase. The preceding words act as modifiers that specify and identify this particular game, creating a single conceptual unit that names a specific, recurring event.
A grammatical analysis reveals the phrase's structure. "Game" is the core common noun. The terms "Patriots Day" and "Boston Red Sox" are proper nouns functioning as noun adjuncts, which are nouns that modify another noun, much like an adjective. "Patriots Day" specifies the occasion of the game, while "Boston Red Sox" identifies the team involved. Together, these elements uniquely define the head noun "game," causing the entire phrase to operate as a singular proper noun.
Recognizing this term as a single noun phrase is crucial for correct syntax and clarity. The entire phrase can be used in a sentence as a single noun would be: as the subject, a direct object, or the object of a preposition. This allows for the construction of grammatically sound sentences where the term is treated as the distinct event it represents, rather than as a disjointed series of words.
