Decentralization means a process where decision-making and accountability are taken away from a central authority. In a Blockchain, there is no central governing body. Independent nodes on the network validate transactions using a system that has been agreed on by everyone.
Think of a field of grass. All the grass plants do the exact same thing they were created for. There is no single grass plant that controls everyone else. And when one or more plants are pulled out, it does not affect the field. The grasses just continue on. That’s the idea behind decentralization.
