The keyword term functions grammatically as a noun phrase. The core of this phrase is the noun "rate," which is modified by the other words to specify a singular, distinct concept. The entire term operates as a single unit to name a specific piece of economic data.
A detailed grammatical analysis reveals that "rate" is the head noun, establishing the phrase's primary part of speech. The word "gold" serves as a noun adjunct, a noun used as an adjective to specify the commodity. The phrase "11th september" acts as a compound adjectival modifier, pinpointing the exact date. These modifiers narrow the general concept of a "rate" to a precise, identifiable subject: the price of a specific commodity on a particular day.
Recognizing the term as a noun phrase is crucial for its application in an article. This classification allows it to function as the subject of a sentence (e.g., "The [term] was recorded at..."), the object of a verb (e.g., "Investors analyzed the [term]..."), or the object of a preposition. This syntactic flexibility enables the term to be the central point of discussion, a specific entity that can be defined, analyzed, and explained throughout the text.
