The keyword term functions grammatically as a noun phrase. In this construction, the head noun, or the primary subject, is "cover." The preceding words, "Patriots Day" and "movie," serve as attributive nouns, which are nouns that act as adjectives to modify the head noun. This entire phrase collectively names a specific, singular object: the promotional artwork for a particular film.
A detailed grammatical analysis reveals a hierarchical structure of modification. The noun "movie" directly modifies "cover," specifying its type (distinguishing it from a book cover or album cover). The proper noun "Patriots Day" then modifies the compound unit "movie cover," identifying the specific film to which the cover belongs. This stacking of nouns creates a compound noun that is precise and self-contained. The entire phrase operates as a single lexical unit, designating a tangible or digital artifact associated with the film's marketing.
Recognizing the term as a noun phrase is critical for article development. It establishes that the core topic is a thing to be described, analyzed, or discussed. Consequently, the article's focus should be on aspects such as the cover's visual design, symbolism, featured actors, typography, and its effectiveness as a marketing tool. In sentence construction, the phrase will function as a subject (e.g., "The [keyword] generated discussion...") or an object (e.g., "The studio designed the [keyword]..."), guiding the narrative to be descriptive and analytical rather than action-oriented.
