* Bright-eyed: This refers to the sparkle and alertness in the eyes of an animal, often associated with youth, energy, and eagerness.
* Bushy-tailed: This describes the appearance of an animal's tail, particularly when it's held high and erect, suggesting confidence and enthusiasm.
It's difficult to pinpoint an exact origin, but it's likely that the phrase evolved over time, drawing from common observations of animals.
Here are some possible explanations for its evolution:
* Early hunters: Hunters may have noticed that animals with bright eyes and bushy tails were often more energetic and alert, making them harder to catch. This association could have led to the phrase being used to describe someone who was full of energy and ready for action.
* Domesticated animals: Farmers and animal handlers may have noticed similar traits in domesticated animals, particularly in young ones. Bright eyes and bushy tails could have been seen as signs of health and vitality, leading to the phrase being used to describe people in the same way.
* Literary influence: The phrase could have been influenced by literary descriptions of animals, where these physical characteristics were often used to portray enthusiasm and energy.
Regardless of its exact origin, "bright-eyed and bushy-tailed" has become a common expression used to describe someone who is enthusiastic, energetic, and eager to start the day.
