The keyword phrase "Patriots' Day 2025 Quebec" functions grammatically as a proper noun phrase. It operates as a single, unified grammatical unit to name a specific entity: a particular statutory holiday distinguished by its name, year, and jurisdiction. As a proper noun phrase, its primary role is to act as a specific identifier rather than to describe a general class of objects or events.
A detailed analysis of its components confirms this classification. The core of the phrase is the proper noun "Patriots' Day," where "Day" is the head noun modified by the possessive "Patriots'." In the context of Quebec, the official name is Journe nationale des patriotes. The numeral "2025" and the proper noun "Quebec" function as post-head modifiers. "2025" is a temporal modifier specifying the year, and "Quebec" is a locational modifier specifying the place. Together, these elements form a complex noun phrase that precisely names one event.
Recognizing the phrase as a noun is crucial for its syntactical use within an article. It can serve as the subject of a sentence (e.g., "Patriots' Day 2025 Quebec is scheduled for May 19."), the object of a verb (e.g., "Residents will celebrate Patriots' Day 2025 Quebec."), or the object of a preposition (e.g., "Information about Patriots' Day 2025 Quebec is now available."). This grammatical function allows the keyword to be the central topic around which complete sentences and ideas are built.
