Probatio diabolica

Probatio diabolica is a really fancy way of saying a test to see if somebody is telling the truth or not. It's like when your parents ask you if you brushed your teeth before bedtime, and you say yes, but they don't believe you. So, they might ask you some more questions and try to catch you lying, just like a test.

But, the word "diabolica" means devilish, so probatio diabolica is a super tricky test that's really hard to pass. It's like when somebody is accused of doing something really bad, and even if they didn't do it, nobody believes them. So, they have to go through a really hard test to prove that they're telling the truth.

Overall, probatio diabolica is a really tough way to see if somebody is being honest or not, and it's not something that you want to have happen to you.
