Forms

energie f (plural energii)[1] The older form energhie (stressed enérghie in Cantemir) is common until the mid-19th century: Ion Budai-Deleanu writes „Apoi fără energhie rămasă” “then left without energy”.[2][3] Heliade-Rădulescu's grammar of 1828 argues for the new form: „trebuie să zicem «patriotism... geografie, energie»” “we must say patriotism, geography, energy”.[2][3]

Etymology

It is borrowed from French énergie, borrowed from New Latin energia (“force in action, activity, efficacy”) as well, as DELR gives it;[3][4][5] DEX gives the same two sources, and MDA2 adds Italian energia, Modern Greek and German.[3][4][5] The Latin word is from Ancient Greek ἐνέργεια (enérgeia), Aristotle's term for activity, actuality, as opposed to δύναμις (dúnamis, “potentiality”); it comes from ἐνεργής (energḗs, “active, effective”), from ἐν- (en-, “in”) and ἔργον (érgon, “work, deed”).[3][1]

The old variant enérghie comes from Modern Greek ενέργεια (enérgeia), and the same form stressed on its third syllable comes from the New Latin word and German Energie.[3] Ciorănescu also takes the 18th-century word from Greek, after Gáldi, and the modern one from French.[6] The sense in physics first appeared in English energy, with Thomas Young, and was fixed by William Thomson in 1850; the everyday senses in Romanian, as in the other modern languages, rest on it.[3] DELR dates Young's use to 1802, Pfeifer to 1807.[3][7]

Earliest recorded meaning

The first record is in Dimitrie Cantemir's Istoria ieroglifică (1705), as enérghie, with the sense “effect, efficacy”: „luând energhiile a le opri” “taking away their force to stop them”.[3][2][8] The form energie appears in 1828, in Heliade-Rădulescu's grammar.[3]

Semantic evolution

In the early 19th century the word meant vigour, force and resolve, of a person or of a people: in 1829 a writer is spurred on „a urma cu mai multă energhie” “to go on with more energy”.[2] Negulici in 1848 glosses it as power, virtue and courage, and Costinescu in 1870 speaks of the energy of the soul, of a remedy and of the muscles.[9][10] The physical sense, the capacity of a system to do work, is in CADE in 1931, and later dictionaries put it first.[11][4] In the plural the word names the physical or moral resources at someone's disposal.[5]
