The keyword phrase "patriot day run savannah" functions grammatically as a proper noun phrase. It operates as a single unit to serve as the specific name of a particular event, distinguishing it from any other run or public gathering.
The structure of the phrase is built around the head noun "run," which identifies the core concept or activity. The preceding words, "Patriot Day" and the subsequent word "Savannah," act as modifiers. "Patriot Day," a compound noun, functions as a noun adjunct specifying the theme or occasion of the event. "Savannah," a proper noun, also functions as a noun adjunct, specifying the geographical location. This construction, where nouns modify a central noun, is a common method in English for creating descriptive and specific titles.
For the purpose of an article, treating this phrase as a proper noun is critical. It should be capitalized consistently as a formal title (e.g., Patriot Day Run Savannah) and used as a single conceptual unit. Within a sentence, the entire phrase will occupy a noun slot, serving as a subject ("The Patriot Day Run Savannah begins at 8 a.m."), a direct object ("Organizers have scheduled the Patriot Day Run Savannah"), or the object of a preposition ("Details about the Patriot Day Run Savannah are online").
