The keyword term functions as a complex noun phrase. Its core grammatical subject, or head noun, is "Patriots Day," which is a proper noun identifying a specific holiday. The entire phrase acts as a single conceptual unit that names a topic with a defined temporal scope.
The component "next 10 years" serves as a post-modifier that qualifies the head noun. This adjectival phrase specifies the precise timeframe of interest. Grammatically, it restricts the subject from the general concept of the holiday to the specific instances of its observance over a future decade. This structure establishes a very specific subject for an article: not the holiday in general, but its schedule and associated events within a particular future period.
Understanding this grammatical role is critical because it dictates that the article's main point must be informational and descriptive, centered on providing data about this noun-based subject. The article should focus on defining or listing the dates and details of the holiday's observance for the specified duration. The structure implies the article's purpose is to be a resource, such as a schedule or a forecast, rather than an argumentative or narrative piece.
