arc

Portion of circumference

The meanings of arc can be collected under the more general idea of a line, usually a curved line: The novel’s story arc reached its apex in the sixth chapter.

Any segment of a circle is an arc, as is the apparent path of a heavenly body or some other projectile across the sky.

An electric arc is the bright, visible bridge discharge of light between two electrodes.

To arc is either to form an electric arc or to follow a curved path, especially through the sky: The baseball arced into the outfield.
