In order to begin to establish the meaning of the vocative term, the first thing we are going to do is determine its etymological origin. In this case, we have to say that it comes from Latin, specifically, it emanates from "vocativus" that can be translated as "relative to call."

The notion is used in the field of grammar to refer to case used for invocation wave ID of an individual.

It should be remembered that grammatical cases they assign a morphosyntactic mark to a certain element of discourse, according to their function in the verbal predicate. The vocative case allows to name the person Directly or get your attention.

Take the case of the expression “Clean your room, Andrés”. In this sentence , "Andrew" It is the vocative that specifies to whom the sender of the message is addressed. In other words, with this vocation it is clear that "Andrew" It is the recipient of the pronounced order.

The vocative can also be an interjection that allows to emphasize the message or initiate the communication . That is what happens with "Che", a term that is usually used in South American countries. For example: "Che, Ricardo, you have to deliver the report before four". In this case, "Che" and "Richard" They work as vocative. As you can see, it would even be possible to do without "Richard", although the receiver specification would be deleted: "Che, you have to deliver the report before four".

In addition to the above, it is worth knowing other curiosities about the vocative, among which we can highlight the following:
-In the Roma, which is the language used by the gypsies, there is a word that comes to indicate the vocative. We are referring to "chabuk", which means "boy".
-In the Valencian, on the other hand, this function of indicating the vocative is developed through the word "che".
-In Arabic, that same task, to come to make clear the vocative, is done by the term "already."
-In the old Castilian, for example, specifically during the Middle Ages, the word “hya” was used in this sense.

In ancient times, certain interjections that acted as vocations allowed to start a talk or open the possibility of a dialogue. If a person entered a home Without knowing if there was anyone inside the property, he could exclaim: "Ah from the house!".

It is important to keep in mind that vocatives appear in other tongues beyond Spanish, although with particular characteristics in each case.
