A more thorough explanation:

Definition: Idem per idem is a Latin phrase that means "the same for the same." It refers to an illustration or explanation that does not add any new information to a matter under consideration.

Example: If someone asks you to explain why a certain law is unjust, and you respond by saying "because it's unjust," you are using idem per idem. This is because you are simply repeating the same thing without providing any new information or explanation.

Another example: If a teacher asks a student to explain why they did not complete their homework, and the student responds by saying "because I didn't do it," this is also an example of idem per idem. The student is not providing any new information or explanation for why they did not complete the homework.

Overall, idem per idem is a term used to describe a situation where someone is repeating the same thing without adding any new information or explanation. It is important to provide clear and concise explanations in order to effectively communicate ideas and information.
