curve

Line without angles

A curve is a line that bends smoothly, without angles.

Roads curve through mountains, rivers curve across plains.

The word extends to anything with such a shape: the curve of a hip, a curve in the road.

To curve is to bend or follow such a path.

A curveball in baseball breaks unexpectedly; to throw someone a curve is to surprise them with something difficult.

To grade on a curve adjusts scores relative to class performance.

Ahead of the curve means anticipating trends before others do.
