The keyword phrase "Xiaomi 14T Pro" functions grammatically as a proper noun. It is the specific, official name designated for a particular entity, in this case, a consumer electronics product.
This classification is derived from its structure and function. The phrase is a compound noun where "Xiaomi" acts as the primary noun (a brand name), and "14T Pro" serves as a post-nominal modifier that specifies the exact model. The entire string, "Xiaomi 14T Pro," operates as a single, indivisible nominal unit. Unlike common nouns which refer to a general class of objects (e.g., "smartphone"), a proper noun identifies a unique and specific member of that class.
In the context of writing an article, establishing "Xiaomi 14T Pro" as the main noun is crucial because it solidifies the product as the central subject. This allows the phrase to act as the subject or object within sentences, enabling the construction of clear, descriptive, and analytical statements about the device itself. For example, in the sentence, "The Xiaomi 14T Pro features an advanced camera system," the keyword acts as the subject, which is the foundational structure for conveying information about the topic.
