The phrase is a compound nominal phrase, functioning collectively as a proper noun. It is not a single part of speech but a combination of elements that name a specific event, document, or announcement. "11 de julio" is a noun phrase specifying a date (July 11th), and "sep" is an acronym for the Secretara de Educacin Pblica (Secretariat of Public Education of Mexico), also functioning as a proper noun.
Grammatically, the phrase serves to identify a particular subject of interest. The date component, "11 de julio," acts as a temporal modifier, narrowing the scope of the subject, "SEP." The entire term operates as a singular concept or identifier. For analytical purposes, it should be treated as the name of a specific occurrence or piece of information, much like "The 2022 Winter Olympics" or "The Treaty of Versailles." The core subject is the governmental body (SEP), and the date pinpoints the specific context or event being discussed.
In practical application for an article, treating this phrase as a proper noun is crucial. It establishes the main point as an event- or document-specific analysis. The article's purpose would be to explain what happened or what was communicated by the Secretariat of Public Education on that particular date. The phrase itself is the subject of inquiry, not a descriptive adjective, a process (verb), or a modifier (adverb). Therefore, the article's structure would be centered on defining, detailing, and analyzing the significance of this specific, named event.
