Etymology: The Greek philosopher Aristotle is the reason this word exists, though he did not use it in its modern sense. His term "energeia" describedActuality, the state of something being fully at work, and Greek writers later built the adjective "energētikós" from the verb "energéō," meaning "to be active," itself from "energós," meaning "active." The Greek sense was about activity and operation rather than a bubbly personality. The word reached English through New Latin "energeticus," which dates to the 16th century, and English speakers used the adjective for a long time in the sense of producing an effect or having force. The "full of energy" sense that dominates today came later, as the noun "energy" grew stronger in English and "energetic" followed it into everyday personal description.
