In the Indonesian phrase "patriot adalah," the keyword "patriot" functions as a noun. The phrase itself represents a predicative construction, not a single part of speech. "Patriot" serves as the predicate nominative (or subject complement), a noun that renames or defines the subject of a sentence.
The grammatical breakdown is as follows: "adalah" is a copulative verb, equivalent to the English verb "is" or "are." Its role is to link the subject to its complement. "Patriot" is the noun that acts as this complement. For example, in the sentence "Dia adalah patriot" ("He/She is a patriot"), "Dia" is the subject, "adalah" is the linking verb, and "patriot" is the predicate noun that defines the subject. Therefore, while the complete phrase is a predicate, the core conceptual term for analysis is the noun "patriot."
For the purpose of an article, this determination is crucial because the main point and subject matter should revolve around the concept of the noun "patriot." The article's focus would be on defining what a patriot is, exploring the attributes, responsibilities, and historical examples associated with the term. The word "adalah" simply serves as the grammatical vehicle to introduce and frame this definition or explanation.
