Word History

Etymology

borrowed from German Neotenie, from Greek néos "young" + -o- -o- + teínein "to stretch, extend" + German -ie -y entry 2 — more at new entry 1, thin entry 1

Note: The word Neotenie was introduced by the German biologist Julius Kollmann (1834-1918) in "Das Ueberwintern von europäischen Frosch- und Tritonlarven und die Umwandlung des mexikanischen Axolotl," Verhandlungen der Naturforschenden Gesellschaft in Basel, 7. Theil, 2. Heft (1884), p. 391. In explaining the coinage, Kollmann inaccurately glossed Greek teínein as "halten, hinhalten" ("hold, hold/put off"), perhaps through confusion with Latin tenēre "to hold."
