Relevant to the Book of Mormon, previous researchers have addressed archaeology, geography, cultural content, DNA, chiasmus, Hebraisms, etc. This work focuses on Book of Mormon language matters and one Native American language family descended from a certain people of the text. After publishing Uto-Aztecan: A Comparative Vocabulary (2011, 2nd edition 2020), which was praised as a new standard in comparative Uto-Aztecan, I also published Exploring the Explanatory Power of Semitic and Egyptian in Uto-Aztecan (2015, 2nd edition 2023). This book draws some data from the larger reference works and proposes (1) that significant amounts of Hebrew, Aramaic, and Egyptian are in the Uto-Aztecan (UA) language family, (2) that UA descends from a mix of the Mulekite and Nephite languages, (3) that the language of the Mulekites shows a Phoenician-leaning, suggesting that they may have come on a Phoenician vessel, (4) that UA provides data relevant to competing opinions among LDS scholars on various Book of Mormon language matters, (5) that Aramaic was Abraham and Israel's original language, not Hebrew, and that Northern Israel's dialects, likely spoken by some of Lehi and Ishmael's ancestors, were heavily Aramaic, (6) that the language picture in the Americas is relevant to Book of Mormon geography, (7) that clarifying comment on a few Book of Mormon names may interest the curious, (8) that more information and new perspectives on DNA and genetic mixes are worth a word, (9) and that a variety of other evidences for the Book of Mormon's authenticity are many.
