The term "mauro zijlstra" functions grammatically as a proper noun. A proper noun is a specific name used to identify a particular person, place, or organization. In this case, it designates a unique individual.
This term is composed of a given name, "Mauro," and a surname, "Zijlstra." Unlike common nouns which refer to a general class of entities (e.g., "footballer," "person"), a proper noun singles out a specific entity. The conventional capitalization of both parts of the name is a primary orthographic signal of its classification as a proper noun. Its linguistic function is to provide a unique and unambiguous reference to a specific person.
For the purpose of writing an article, recognizing this term as a proper noun is fundamental to correct sentence construction. It will function as a noun and can therefore act as the subject of a verb (e.g., "Mauro Zijlstra joined the team."), the direct or indirect object (e.g., "The coach selected Mauro Zijlstra."), or the object of a preposition (e.g., "All eyes were on Mauro Zijlstra."). It cannot function as a verb, adjective, or adverb without modification.
