what is the original theory of Beat around the bush

The original theory of "beat around the bush" is not a formal or academic theory, but rather an idiomatic expression that means to avoid addressing a topic directly or to speak in a vague or evasive manner. The phrase is believed to have originated from hunting practices in medieval England. Hunters would hire beaters to drive animals out of the bushes or undergrowth, making it easier for the hunter to catch them. However, some animals would try to escape by circling back into the bushes, forcing the beaters to "beat around the bush" to flush them out again. Over time, this phrase came to be used metaphorically to describe someone who avoids getting to the point or discussing something directly.
