11 Septiembre De
The phrase "11 septiembre de" is an incomplete noun phrase (in Spanish, sintagma nominal or frase nominal). Its primary function is to act as a noun within a sentence. The core of this construction is the noun "septiembre" (September), which is modified by the numeral "11." The preposition "de" (of) is included to connect this date to a specific year, which is absent in the provided fragment. In Spanish, the standard grammatical structure for a full date is `[numeral] de [month] de [year]`, for example, "11 de septiembre de 2001." The provided phrase is a fragment of this structure. The head of the phrase is the noun "septiembre." The number "11" functions as a determiner, specifying the day. The final preposition "de" signals the beginning of a prepositional phrase that would modify the date, typically by adding the year. Without the year, the phrase is grammatically incomplete but its function as a nominal unit remains. ...
