n.
Any of a group of widely occurring yellowish-brown to black iron oxide minerals, essentially FeO(OH)·nH2O, used as a minor ore of iron.

[Originally, bog iron ore, from German Limonit (coined on the model of German Wiesenerz : Wiesen, meadow + Erz, ore) : Greek leimōn, meadow, moist grassy place (of unknown origin) + German -it, -ite (from Latin -ītēs; see -ite1).]
