The legal (mechanical) rules that are included in the civil law are considered as general rules directed to every understanding of a specific legal text, such as the rule (it is undeniable that the terms change with the change of time), or as rules of interpretation of the text, whether for contracts, or any linguistic text, such as the rule (what matters are the purposes and meanings, not the words and buildings), so they are rules. It falls within the scope of (understanding and applying the legal rule), most of which emanate from the legal mechanistic sciences, such as the science of the principles of jurisprudence, logic, and linguistics. These sciences are termed the mechanistic sciences, because they are sciences that serve others. This is what we notice in the rules of interpretation, as they are distinguished from the substantive and procedural rules contained in the texts. Legislation changes with time and place in its content, ruling, and function.
