An arrow groove is a groove or canal that makes it easier for an arrow to slide off and hit a target. In archery, the arrow groove is also known as a nock groove or arrow notch. However, there are other words that can be used to describe the arrow groove, such as a bow channel, arrow track, arrow path, and shaft channel. These synonyms are often used interchangeably depending on the context, but ultimately serve the same purpose - to provide a secure and precise guide for the arrow to follow towards its intended target.
