In the Book of Ether we hear that Jared and his brother feared the confounding of their language and the brother of Jared prayed that the language of his brother and their friends would not be confounded(Ether 1:33-35).
In 1828, the word confound meant to "to mingle and blend different things, so that their forms or natures cannot be distinguished; to mix in a mass or crowd, so that individuals cannot be distinguished."
What's more, in Ether and unlike Genesis, Jared's family and friends see this mixing coming a mile away. So we have "a great tower", "scattering" and language mixing.
None of this is remarkable in and of itself since Moroni is making the connection between the early Jaredites and the language myth of Genesis.
Now, we know that the world's languages, from Chinese to Tongan to Spanish to Arawak don't come from Mesopotamia, because of some linguistic Cambrian explosion 5,000(?) years ago. So how do we make sense of the tower, scattering and language mixing found in Ether 1?
In one of my past posts, The End of the Jaredites, I made a case for having the Jaredites arrive in the New World at around 2350 BC. So imagine my pleasant surprise when I just realized that Sumer was conquered by the Akkadians, a Semetic speaking people led by Sargon of Akkad, in 2334 BC. Also, as early as 2500 BC, many Akkadian loan words had already crept into the Sumerian language.
Maybe, just maybe, Jared and his people were fleeing Sargon of Akkad, or at least Akkadian influences on what they perceived to be pure Sumerian culture, what they perceived to be the pollution of their language. Certainly, according to my scheme, they left during Sumer's decline. Could this be the historical core beneath Moroni's telling of Jaredite ethnogenesis? Maybe.
