Full of beans
Meaning
To be full of energy, enthusiasm, or vivacity.
Origin
In the 19th century, farmers and horse breeders understood the potent energy boost that beans provided to their working animals. Broad beans, in particular, were a common and highly nutritious feed for horses, known for making them spirited, lively, and yes, 'full of beans.' This literal observation of an energized equine, prancing and eager for action after a good feed, quickly galloped into the English lexicon, becoming a charming way to describe any person brimming with enthusiasm and restless energy.
Examples
- After a good night's sleep, the children were full of beans and ready for a day at the park.
- The young colt was so full of beans, prancing around the field with boundless energy.
