” … say that ‘good’ is among the most important (terms) in use … we say from the Saxon, “good”; the Dane, “god”; the Goth, “goda”; the German, “gut”; the Dutch, “goed”; the Latin, “bonus”; the Greek, “kalos”; the Hebrew, “tob”; and the Egyption, “mon.” Hence, with the addition of “more,” or the contraction, “mor,” we have the word “mormon”; which means, literally, “more good.

Concerning the meaning of “Cumorah,” there has been some study, and Paul Hoskisson on the FARMS website concludes with the following:

“In summary, there are several possible explanations for Cumorah. Two, namely a derivation from Gomorrah and a feminine form of kmr meaning “mound,” seem to work well, both from a linguistic standpoint and from etymological appropriateness. Two other proposals do not seem to work well, mainly for linguistic reasons. The last suggestion, “[Unacceptable] Priesthood Hill,” could work linguistically and, with a stretch of the imagination, might be explained appropriately.”

Cumorah – If the hill Cumorah where the great battles took place was the Cerro Vigia down in Mexico, and if Vigia is the spanish translation of the original ancient name of the hill, then Cumorah could possibly mean something like: ‘Place of the Overwatch’ or something similar. ‘Vigilar,’ in spanish means, ‘to watch over.’
It’s just a guess, of course, but it’s interesting.

Mormon – Brandt Gardner, in his commentary of the Book of Mormon, points out that Mormon was most likely named after the land of Mormon, where God restored the covenant with Alma the Elder. Therefore, the word Mormon might refer to the restoration of the covenant. The Book of Mormon might be: “The Book of the Restoration of the Covenant,” a very fitting title, given its purpose in these latter-days.
