The word prelation comes from the Latin praelatio, which means priority or preference. This term is a cultism little used in colloquial language .

in the legal field
In the legal field there is the so-called right of prelation. It consists in understanding that one person has some kind of preference or privilege over another.
The order of prelatation of laws is fundamental to understanding any legal system of a nation.
The idea of prelation in law is based on the priority of some laws over others. As a general criterion, this ordering of laws consists of establishing the law with the highest hierarchy and a level inferior to the laws of lesser importance.
In other words, starting from a fundamental norm (for example, the text of a constitution ) it is possible to develop other secondary norms. If there was no order of precedence in the laws, any kind of conflict could occur, since it would not be easy to establish the law that should be applied in each case.
A matter of paramount importance is the establishment of legal sources, from which they present an order of prelation. Thus, at a higher level are international treaties, then national constitutions, and then laws and regulations.
When organizing the computer programming language , it is also necessary to establish an order of prelation, that is, of priorities. In computer language we speak of the prelation tree.
