An ogee is a fancy word for a shape that looks like an "S" that has been curled up very tightly. Imagine a long, flat piece of clay or playdough that you can roll up into a snake. If you then bend that snake into a tight "S" shape with curvy edges that go in and out, that's an ogee.
The ogee shape is often used in architecture, where it can be seen in things like arches, doorways, or moldings. It's also used in furniture and decoration, like on picture frames or mirror frames.
Overall, an ogee is just a fancy, curvy shape that can add some extra style and elegance to things like buildings and furniture!
