From Book of Mormon Onomasticon
Variant spelling of IRREANTUM
- O: Irreantum > Irreaantum >- Irreantum
- P, 1830-1981: Irreantum
- Discussion: Irreantum was immediately changed to Irreaantum, then later back to Irreantum in O. This is perhaps because Cowdery inserted another a when he thought he had missed the a in the word, but later realized he had not, and corrected it. This spelling, Irreantum, is also consistent with other Book of Mormon names, such as Neas and Teancum.
