There is — when to use
“There is” is used when we want to say that one thing exists in a particular place. It’s like pointing out a single item. For example, if you have a room with a bed, you would say, “There is a bed in the room.” You’re focusing on the presence of just one thing.
There are — when to use
“There are” is used when we want to say that multiple things exist in a particular place. It’s like pointing out more than one item. If you have a room with a bed, a chair, and a desk, you would say, “There are a bed, a chair, and a desk in the room.” Here, you’re acknowledging the existence of several things.
