Assyrian law is like a set of rules that the people of Assyria, who lived long time ago, used to follow. It was their way of governing their society and making sure everyone behaved in certain ways.
Imagine you are playing a game with your friends, and you make some rules so that everyone can play fairly. In the same way, Assyrian law had rules that everyone had to follow.
For example, one of the rules was "an eye for an eye." This meant that if someone did something wrong, they would be punished with the same bad thing they did to someone else. So if someone hurt someone else's eye, they would also lose their own eye as punishment.
Another rule was that if someone stole something, they would have to pay back more than they took. This was called "restitution." So if someone took something worth 10 coins, they would have to pay back 20 or more coins.
Assyrian law was very strict, and people who broke the rules were punished severely. But it was also meant to keep people safe and make sure everyone was treated fairly.
Overall, Assyrian law was an important part of their society, and it helped them maintain order and justice.
