In order to determine the meaning of the word at hand, the first thing we have to do is know its etymological origin. In this case we can say that it derives from Latin, in particular it comes from the term "vallum", which can be translated as "palisade."
We also have to emphasize that, at first, it was used as a military term, since in the second century the Romans proceeded to build two fences to protect themselves and gain security. We are referring to what became known as Antonini Vallum (Antonino Wall) and Vallum Hadriani (Hadrian's Wall).
A fence is a siege that is armed with different stakes or obstacles to protect or close a determined space .
For example: "The police installed a fence so that the public can not approach the stage", “We are going to have to put a fence in the garden so that dogs and stray cats do not enter”, "The young man wanted to jump the fence to escape, but was caught".
Usually a fence looks for prevent an intruder from entering a place . The owner of a home that has a garden can install a fence to prevent people Enter your property. A farmer, meanwhile, can place fences to delimit his land.
There are different types of fences. The most popular are those made with wooden boards : the vertical boards are nailed to the ground and placed at a certain distance from each other, staying together through horizontal boards. There are also metal and plastic fences.
In addition to those mentioned, we have to mention other types of fences that are also relevant. Specifically, we are referring to these three:
-Electrified fence. As the name implies, it is a structure or fence that works based on the principle of electric shock. It is used as a protection and safety measure, since whoever comes to touch or touch it will suffer a discharge. In plots to prevent intruders or animals from escaping you can find this kind of fence.
-Valla for pets. It is a unique device that is presented in a collar format and that is placed on the cat or dog in question. Its objective is not another that does not move away from the space where it is indicated, since if it exceeds those limits it will receive a slight discharge.
-Valla for children. Under this name is a safety device that is placed on balconies, terraces and stairs, for example, to prevent children from falling.
In the field of sport , the fences are the obstacles that athletes must jump in certain competitions, such as hurdle races (100 meters fences , 400 meters fences , etc.) and the Equestrian jumping (where the horse, guided by a rider, has to jump fences).
The billboards Finally, they are posters that are installed in public spaces to promote different products : "The Spanish company will pay one million euros a year to have its logo appear on the billboards of the stadium".
