Word History

Etymology

borrowed from New Latin, from Greek dysprósitos "difficult to access" (from dys- dys- + prósitos "approachable," verbal adjective of próseimi, prosiénai "to go toward, approach," from pros- pros- + eîmi, iénai "to go") + New Latin -ium -ium — more at issue entry 1

Note: The element was named by the first person to isolate it, the French chemist Paul Émile Lecoq de Boisbaudran (1838-1912), reported in "Le holmine (ou terre X de M. Soret) contient au moins deux radicaux métalliques," Comptes rendus hebdomadaires des séances de l'Académie des Sciences, tome 102 (janvier-juin 1886), pp. 1003-04. The name was apparently given because several hundred fractionations ("plusieurs centaines de fractionnements") were required to isolate a sufficient amount of it to test spectroscopically.
