cone




A cone is a shape that has a circle at the bottom and sides that narrow to a point, like a party hat, a rubber pylon at a construction site, or, yes, an ice cream cone.

Why is a cone called a cone? The Latin word conus means “the peak of a helmet,” which must have described the shape of this type of hat in the 16th century. The Greek konos means “spinning top” and “pine cone.” Both of these objects have one wider end that tapers to a point, describing a cone very accurately.
