Forms: 1800s rancierite, 1900s– rancieite, 1900s– ranciéite.

Origin: A borrowing from French. Etymons: French ranciéite, rancierite.

Etymology: < French ranciéite (1900), alteration of †rancierite ( A. Leymerie Cours de minéral. (1857) ii. 329) < Rancié (formerly also †Rancier ), name of the mountain near Vicdessos, Ariège, France, where the mineral was first found + -ite -ite suffix¹.

Mineralogy.
