Linguistics and the Book of Mormon

The professed doctrine of most denominations within the Latter Day Saint movement is that the Book of Mormon is a 19th-century translation by Joseph Smith of a record of ancient inhabitants of the American continents, written in a script which the book refers to as "Reformed Egyptian". There is no evidence of a language matching this description nor any evidence of Old World linguistic influences in the New World whatsoever.
