Where does an arrow rest if no arrow rest is provided on a bow?

An arrow typically rests on the ledge at the base of the sight window when no arrow rest is provided on a bow. This position allows the arrow to maintain a proper alignment and stability while being drawn and released. The sight window is designed to facilitate sighting and aim while also providing a slight ledge for support.

Choosing to rest the arrow on the bowstring or in the archer's hand would not provide the necessary stability for consistent shooting. Resting on the ground would not be practical for launching the arrow and would likely result in misalignment or inconsistency. The ledge at the base of the sight window is specifically structured to be the most effective support point for an arrow in these circumstances.
