The form of something gives it its shape. Basic shapes include the square, the circle, and the triangle. You may have a nose the shape of a ski slope.

When you admire someone's shape, you're admiring their form, or their body. When you're out of shape or vowing to get back into shape, you're using shape to refer to your physical stamina or overall health. You can shape something by giving it form, as in "shape the dough into a braided twist," or influence someone, as in a teacher who shapes young minds.
