What does the term 'bight of reins' imply in equestrian terminology?

The term 'bight of reins' refers specifically to the looped section of reins that is formed when the reins are not pulled tight. This creates a flexible area that allows the rider some ability to manage the reins without constricting the horse. Understanding this term is important for instructors and riders alike, as managing the bight can impact communication with the horse. The bight allows for a softer feel and is essential for subtle cues, enabling a more effective riding experience.

The other options do not accurately describe the concept of a bight in this context. A saddle is a separate piece of equipment integral to riding, the part connected to the bit refers to the attachment point for reins on the horse's bit, and how reins are held relates to the technique or methodology of rein handling rather than the specific term 'bight.' Each of these alternatives takes the focus away from the specific feature of the reins itself, which is captured by the correct answer.
