Alright kiddo, let me try to explain it to you in a way you can understand.
Absolution of the dead is a religious practice that happens after someone has died. Some people believe that when someone dies, their soul goes to a special place called heaven, but sometimes they might not be allowed in because of the bad things they did when they were alive.
That's where absolution comes in. It's like asking for forgiveness on behalf of the person who has died so that their soul can be allowed into heaven. Think of it like saying sorry to your friend if you did something wrong, but instead of saying sorry to your friend, you're saying sorry to God so that the person who died can go to heaven.
Sometimes, people have to perform certain actions or say special prayers to make sure that the person who has died is forgiven for their sins. It's like doing a chore to make up for something you did wrong.
The idea behind absolution is to make sure that the person who has died is at peace and can be with God in heaven. It's a way of showing love and respect for someone even after they have died.
