Grammatically, the phrase "tanggal 11 september 2025" is classified as a noun phrase. It functions as a single conceptual unit to name a specific entity: a particular calendar date. The head word of the phrase is "tanggal" (date), which is a noun, and the subsequent numerical and nominal components ("11 september 2025") serve to specify and identify that noun.
A detailed analysis of its structure reveals that "tanggal" is the head noun, which is post-modified by the specific date "11 september 2025." This modifier acts as an appositive, renaming or clarifying the head noun. While the entire construction is a noun phrase, its syntactic function within a sentence is typically that of an adverbial phrase of time (or a temporal adjunct). In this role, it modifies a verb, adjective, or clause by answering the question "When?". For instance, in the sentence "The conference will be held [on] tanggal 11 september 2025," the phrase modifies the verb "held."
Understanding this classification is essential for content creation. By identifying the term as a noun phrase, it can be correctly employed as a subject (e.g., "Tanggal 11 september 2025 marks the anniversary"), an object (e.g., "We have scheduled the launch for tanggal 11 september 2025"), or the object of a preposition. This grammatical flexibility allows the keyword to be integrated seamlessly and accurately into various sentence structures, ensuring the article is both coherent and optimized for natural language processing systems that parse information based on grammatical roles.
