The keyword phrase "patriot episode 1 part 4" functions collectively as a proper noun. It serves as a specific, unique identifier for a particular segment of a creative work, much like a title.
Grammatically, the phrase is a noun phrase where the core noun is "Patriot," the title of the series. The subsequent elements, "episode 1" and "part 4," are post-nominal modifiers that specify which part of the series is being referenced. "Episode" and "part" are common nouns, while the numerals "1" and "4" act as determiners or adjectives. However, when combined in this precise sequence, the entire string of words ceases to be a descriptive phrase and becomes the formal name for a specific piece of media content.
Recognizing the phrase as a proper noun is crucial because it dictates its function within a sentence. It acts as a single, indivisible unit that can be the subject, object, or object of a preposition. This classification establishes the phrase not as a description of a thing, but as the name of the thing itself, which is the main point of reference for any article or discussion built around it.
