“Hebrew scholar and grammarian William Chomsky concluded that ‘two main factors generally operate as controls in the process of linguistic change: (1) isolation and (2) possession of written records.’ Because the people of Zarahemla had been so long isolated and without written records, their language had understandably deteriorated to the point that the people of Mosiah could not communicate with them” (Ogden and Skinner, Book of Mormon, 1:296–97).
