(1745-1801) A New England theologian and philologist, Edwards was a pioneer in the comparative linguistics of North American aboriginal languages.

Observations on the Language of the Muhhekaneew Indians, in Which the Extent of that Language in North America is Shewn, its Genius is Grammatically Traced, Some of its Peculiarities, and Some Instances of Analogy between that and the Hebrew are Pointed out.
