The term is a composite of a cardinal number ("911") and a German noun ("Jahre," the plural of "Jahr," meaning "year"). Grammatically, the entire phrase functions as a noun phrase. Its primary role is to name a specific quantity or duration of time, effectively acting as a single noun unit in a sentence.
In syntactical analysis, the number "911" serves as a determiner or numeral adjective that quantifies the head noun, "Jahre." As a complete noun phrase, this unit can function as the subject of a sentence (e.g., "911 Jahre sind eine lange Zeit"), the direct object of a verb (e.g., "The city celebrates 911 Jahre"), or the object of a preposition (e.g., "a history of over 911 Jahre"). This structure is standard in both German and English for expressing specific quantities of countable nouns.
Understanding this classification is crucial for proper article construction. Treating the keyword as a noun phrase ensures it is used correctly to represent a concepta specific periodthat can be the subject of discussion, analysis, or commemoration. This prevents grammatical errors, such as attempting to use the phrase as an action (verb) or a standalone descriptor (adjective), thereby maintaining professional clarity and precision when writing about events or histories related to this time span.
