"ADJUST: You change something a little bit, if this word is mentioned. But what you’d do would really depend on what came before the adjustment and what came after it. Anything that isn’t fitting to the horse would cause a person to think about adjusting what they were doing.
The word “adjustable” is connected real close to this word, and that’s the way you want to have the hindquarters on your horse. You’d need to be able to change those hindquarters around through feel, wherever you needed them to be, and in some cases they would need to be real adjustable right on the spur of the moment."
