What is one reason that roger williams wrote a key into the american language?

Roger Williams was known as a believer in separating Church from State and he was noted for his tolerance of racial and religious differences. One reason why he decided to write a key into the American Language, was so that settlers would be able to communicate more effectively with Native Americans; as a promoter of tolerance and equality, Williams helped promote more stable interactions between settlers and Native Americans.
