The keyword term "patriot day pictures" functions as a noun phrase. The primary part of speech, which serves as the main point or grammatical head, is the noun "pictures." The words "Patriot Day" act as a compound adjectival modifier, specifically a noun adjunct, which specifies the type or subject of the pictures. Therefore, the core subject of an article using this keyword is the images themselves.
A grammatical analysis breaks the phrase into its core components. The head noun is "pictures," which establishes the subject matter as visual representations. The preceding nouns, "Patriot" and "Day," form a proper noun that functions attributively. In English grammar, a noun used to modify another noun is called a noun adjunct or attributive noun. Here, "Patriot Day" modifies "pictures" by defining their context, theme, and occasion, narrowing the focus from general images to those specifically related to the observance of Patriot Day.
For practical application in an article, this grammatical structure dictates that the content must center on the visual media. The article's purpose should be to present, analyze, or discuss the photographs, illustrations, or other imagery associated with the commemoration. The modifier "Patriot Day" provides the essential context, but the fundamental subject remains the collection of images. The keyword is not an action (verb) or a simple descriptor (adjective) but a specific subject to be explored.
