Until Latin we must leave, symbolically speaking, to be able to find the etymological origin of the central term that now concerns us. In doing so, we discover that it comes from the word “centralis”, which is made up of two components: the noun “centrum”, which is synonymous with “center”, and the suffix “-al”, which is equivalent to “relative to” .

Central is that belonging or relative to center . This term has a great variety of uses: it can be the equidistant interior point of the limits of a figure or a surface; of the space where coordinate actions converge; from the region that concentrates the busiest streets of a population; of the institute that develops research or studies; of the end for which he feels attraction; or of objective to which one aspires.

Most of these meanings can be linked to the notion of central. The central, therefore, can be something that is in the physical center . For example: "The central shelf is somewhat arched, we would have to take weight off of it", “All those paintings are beautiful, but the one I like the most is the central one”.

He place that is between two extremes It is also known as central: “The most beautiful beaches in the world are in Central America”, "I am not sure which countries are part of Central Europe".

The facilities where it is produced electric power they also receive the name of central, beyond the means they use: "Protesters asked to close the nuclear power plant", “The construction of a hydroelectric plant always generates changes in the environment”.

Nor can we ignore that this word we are analyzing is inextricably linked to certain words to create a very specific term. Thus, for example, is the one known as central heating, which is the one that is identified because it gives heat to an entire building from a single focus.

In the same way, there is the Central General Staff. It is a military agency that becomes the superior both in what would be the Navy and the Army.
