Energy

/ˈɛnərdʒi/ noun

Definition

The strength or power that allows things to move, change, or do work. It can describe both physical power and a person’s liveliness or enthusiasm.

Etymology

From French *énergie*, from Latin *energia*, from Greek *energeia* ('activity, operation'), from *energos* ('active'), from *en-* ('in') + *ergon* ('work'). It originally meant 'being in action.'

Kelly Says

In physics, energy is the ability to do work; in daily life, we feel it as 'I can do things' or 'I’m exhausted.' The same word connects sunlight, electricity, coffee buzz, and motivation—it’s all about potential turning into action.
