A livery stable is like a big house for horses. It's a place where people can bring their horses to live and be taken care of while they're not using them.
So, imagine you have a horse, and you need somewhere to keep it when you're not going for a ride or using it for anything. You could keep it in your backyard, but that might not be very convenient or safe. That's where a livery stable comes in.
At a livery stable, there are stalls for horses to rest in, and there's a big barn where they can stay out of the weather. People who work at the livery stable will feed the horses, give them water, and clean up after them. They might even groom them and take them for walks or rides if the horse's owner isn't able to.
Livery stables can also be a place where people who don't have their own horses can go to rent one for a ride. It's like going to a car rental place, but for horses.
Overall, a livery stable is a safe and comfortable place for horses to stay, and it provides a lot of convenience for their owners.
