Deconsecration is like taking away a special sticker or toy from a kid. In specific places like temples, churches, or religious sites, there are things or areas that are considered holy or special. Deconsecration happens when people remove or take away that special or holy status from those places or things. For example, if a church decided to stop being a church, they would need to do deconsecration by removing or changing things like the altar, holy water, or crosses so that they are no longer considered special or holy. This is similar to taking off a special sticker from a kid's toy, so it is just like any other toy.
