spiral

A spiral is a coil or curl, like the shape of a piece of hair wound around your finger, a Slinky toy, or a corkscrew.

A curve forming a series of circles that become gradually larger or smaller is one kind of spiral. You can also use the word as a verb when something moves in a spiral shape: "Then the wind died and I watched my kite spiral down to the ground." The origin of spiral is the Medieval Latin spiralis, which means "winding or coiling," from a Greek root: speira, "coil, twist, or wreath."
