The keyword term "11 sep calendar" functions grammatically as a noun phrase. In this construction, "calendar" is the head noun, which identifies the core object or concept. The preceding component, "11 sep," is a noun adjunct (or attributive noun) that modifies the head noun, specifying its type, subject, or theme. It operates adjectivally to distinguish this calendar from any other.
Understanding this grammatical structure is essential. The phrase does not represent an action (verb) or describe a quality of another noun (adjective) but instead names a specific entity. The relationship between the words is hierarchical: "11 sep" narrows the broad category of "calendar" to a particular instance related to the date September 11th. This is a common pattern in English for forming compound nouns, similar to phrases like "kitchen table" or "project manager," where the first noun specifies the function or context of the second.
For the purpose of an article, identifying "11 sep calendar" as a noun phrase establishes the main point as a specific subject to be defined, described, or analyzed. The article's focus should be on explaining what this particular calendar iswhether it's a historical timeline of the events of September 11th, a schedule for commemorative events, or a conceptual tool for organizing information related to that date. This grammatical determination dictates an expository approach centered on the subject itself, rather than an action or a description.
