When you twist something, you turn it in a different direction. You might twist off a bottle cap, or you might even twist the plot of a story you are writing.
A kite's tail twists in the wind, curling around itself, and a baker twists a piece of dough into a pretzel shape. You can also twist out of someone's grasp (to escape your godmother's cheek pinching), or twist your ankle hurrying away. As a noun, twist means a bent and curved shape, like the twist of a curl or a twist of soft serve ice cream. In a book or movie plot, a twist is a shocking development.
