The keyword phrase "patriots championship" functions as a noun phrase. The primary part of speech, which serves as the main point or head of the phrase, is the noun "championship." The word "Patriots," itself a proper noun, acts as a noun adjunct.
A noun adjunct, also known as an attributive noun, is a noun that modifies another noun, functioning similarly to an adjective. In this construction, "Patriots" specifies the type of championship being discussed, answering the question, "Which championship?" It modifies "championship" by associating the event directly with the Patriots team. This grammatical structure creates a specific, compound concept, treating "patriots championship" as a distinct category or event title, much like "World Series" or "Super Bowl."
For the purpose of writing an article, recognizing "championship" as the core noun is crucial. The entire noun phrase will function as a subject, direct object, or object of a preposition within your sentences. This ensures that the article's focus remains on the event of the championship, with "Patriots" providing the specific and necessary context for that event. All surrounding language should be structured to support this central concept.
