Hebrew, מורמן. A word of unknown origin translated by the Holy Spirit as “a wild or untamed place,” or “wilderness.” According to Gordon Thomasson, the toponym Mormon (MRMN) and the toponym Hermounts (HRMN) might be the same word, and can be found in the Book of Mormon referencing a wilderness infested by wild beasts: “...a place which was called Mormon, having received its name from the king, being in the borders of the land having been infested by times, or at seasons, by wild beasts” (Mosiah 9:32 RAV, 18:4 OPV). In addition, both Mormon and Hermounts may share the root RMN.
