The keyword term "september 11th zodiac signs" functions grammatically as a noun phrase. The core of this phrase is the plural noun "signs," which serves as the headword and identifies the primary subject being discussed.
In this construction, the head noun "signs" is modified by the preceding words which specify its context. The word "zodiac" is an attributive noun, functioning as an adjective to classify the type of signs (astrological signs). The date "september 11th" acts as a specific adjectival modifier, narrowing the topic to the sign or signs associated with that particular day. The entire phrase operates as a single conceptual unit that names a specific topic.
This grammatical determination is critical because it establishes that the main point of the article must be informational and definitional. By identifying the keyword as a noun phrase, the article's objective becomes to answer the implicit question, "What are the zodiac signs for September 11th?" The content should focus on identifying the specific sign (Virgo), describing its traits, and providing related astrological details, thereby explaining the subject named by the keyword.
