To have energy to burn
Meaning
To possess an exceptional abundance of physical or mental vigor, often leading to a restless desire for activity.
Origin
The vivid image behind "to have energy to burn" comes from the literal act of combustion. Think of a roaring fireplace or an engine consuming fuel: if there's "fuel to burn," it means a lavish excess, more than is immediately needed. This sense of abundant supply, enough to expend freely without fear of running out, readily translated to human vitality. As the 20th century progressed and "energy" became a common descriptor for human vigor, the phrase took hold. It painted a picture of someone with such a profound surplus of stamina and enthusiasm that they could metaphorically "burn" it off through endless activity, much like an inexhaustible fuel source, without ever seeming to diminish their own vibrant reserves.
Examples
- After a good night's sleep, the children had energy to burn and immediately ran out to play in the park.
- Even after working a full day, she still had energy to burn, so she decided to go for a long run.
