Etymology

It is borrowed from Ancient Greek ἐνέργεια (enérgeia, “activity, operation”),[2][3][4] from ἐνεργής (energḗs, “active”), from ἐν (en, “in”) and ἔργον (érgon, “work”).[4][5]

Earliest recorded meaning

Jerome uses it in his letters.[2][6] Köbler dates Jerome c. 383–419/420 AD.[4]

Semantic evolution

It was a late word for energy, efficiency or force, in Jerome and other Church writers.[2][3][6] Isidore uses it as a figure of speech, the vivid presentation of events as if before the eyes.[7]

In medieval Latin it was power, operation, efficacy, force and authority, and also inspiration.[8] British writers used it of energy and strength and, in philosophy, of actuality.[9] English energy is recorded in the 1590s as force of expression, through French énergie.[5]
