VAIN

In order to begin to delve into the establishment of the meaning of the vain term that concerns us, we must first discover its etymological origin. In this sense, we can say that it is a word that derives from Latin, from the adjective “vanus”, which can be translated as “empty”.

It is an adjective that can be used with different meanings depending on the context.

Something qualified as vain may lack substance, core , support or foundation . For example: "The president gave a vain speech, which does not provide any useful data" , "I am tired of hearing vain messages and without content on television" , "The new architect presented me with a vain project, impossible to support" .

The adjective can also be applied to that which is insignificant, useless or useless : “The bird made some vain attempts to try to escape from the trap, but finally got tired” , “Lifting a few bottles from the beach may seem like a vain job, although any contribution that is made to the environmental struggle, no matter how small, is important ” , “ It is a vain effort, but I feel that I must do it ” .

When something is done that does not achieve the expected effect or that does not allow the desired result to be achieved, it is often said that it is an action "in vain" : "The woman asked for help in vain since no one came to assist her" , "The 27 points of Manu Ginobili were in vain because his team fell in overtime" , "The television channel made a millionaire offer in vain to the actor, who did not accept since he had planned to take a year off . "

Within the religious sphere, the term in question occupies an important role, since it appears in what is the second of the ten commandments in the Catholic religion. We are referring to the one that states that "you shall not take God's name in vain," which means that God's name should not be used in phrases or exclamations that are not to honor him.

In architecture , finally, it is called vain to the hollow space that interrupts a solid surface: "The castle is almost destroyed, but still can be seen the doorways and windows" .

In Mesopotamia it seems that the origin of this architectural element is already found, which can be of very different types, depending on the form they acquire. Hence, they can be found from rhomboids to circular ones, among others.

In the same way, we cannot forget the existence of what is known as an electrical span. It is a term that refers to the separation that must exist between what are the different conductors that exist in the laying of a transmission in high and medium voltage. That is, the distance between support and support.
In addition, there is also what is called the engine compartment, which refers precisely to the hole or space in which the engine is placed and which is located under the hood.
