Inviolability means that something cannot be harmed or changed. It is like when you put your toys away in a special place where no one can touch them without your permission. Your toys are inviolable because nobody can take them, break them, or change them without your say-so.
In the world of adults, inviolability means that certain things are protected and cannot be messed with without the right permissions. For example, a person's body is inviolable, which means that no one can touch or hurt them without their permission. This is why we have laws against hurting other people or doing things to their bodies without their consent.
Other things that can be inviolable include physical spaces like someone's home, private information like passwords or medical records, and personal beliefs like religion or political views. All of these things are important to people, and they can be protected by laws or rules to make sure that they remain inviolable.
In summary, inviolability means that certain things are protected and cannot be touched, hurt, or changed without permission. Just like your toys are inviolable in your room, there are lots of things that are inviolable in the adult world to keep people safe and happy.
