The keyword term "patriot day full cast" functions grammatically as a noun phrase. It operates as a single conceptual unit to name a specific entity: the complete list of actors associated with the film titled Patriots Day. The core noun of the phrase is "cast," which is modified by the adjective "full" and the attributive proper noun "Patriots Day."
In this construction, the proper noun "Patriots Day" acts as a noun adjunct, specifying which "full cast" is being referenced. The head of the entire phrase is the noun "cast." This grammatical structure allows the multi-word term to serve as a subject or object within a larger sentence, such as, "The Patriots Day full cast includes many notable actors." This compositional nature is common in English for creating highly specific and descriptive nominal groups.
Identifying the term as a noun phrase is critical for content strategy and information retrieval. It signals a clear user intent to find a definitive list or a set of data (a "thing"), rather than an action (verb) or a quality (adjective). Consequently, an article designed around this keyword should be structured to directly provide this information, treating the cast list as the primary subject matter to satisfy the user's query for a specific informational entity.
