The keyword term "patriots day script" functions as a noun phrase. The main part of speech, which serves as the grammatical head of the phrase, is the noun "script."
In this construction, "Patriots Day" acts as a noun adjunct (or attributive noun). It modifies the head noun "script" by specifying its type or subject matter. The phrase is not describing a script that is "patriotic"; rather, it refers specifically to a script related to the subject of "Patriots Day," whether it be the holiday or the film of the same name. This grammatical structure is common in English, as seen in examples like "kitchen table" or "business plan," where the first noun specifies the function or category of the second noun.
Identifying "script" as the core noun is crucial because it establishes the primary subject. Any analysis, search query, or discussion using this term is fundamentally about a written document (a script). The modifier "Patriots Day" simply narrows the focus to a specific instance of that document type. Therefore, the term's syntactic function in a sentence will be that of a noun, capable of acting as a subject, object, or complement.
