Social: Mormon introduces an inserted letter from Moroni. We do not know how widespread literacy was among the Book of Mormon peoples, but certainly Moroni is literate (or has access to scribes, a possibility even though it is not mentioned). It is also assumed that Ammoron will be literate, or at least have access to someone who can both read and right. Finally, there is the expectation that the language and script will be able to be read by Ammoron. We cannot tell whether this presumption of understanding comes because Moroni knows Ammoron is a Nephite apostate, or because there was some type of lingua franca between the Nephites and Lamanites.
