Little of the Susquehannock language has been preserved. The only source is a Vocabula Mahakuassica compiled by the Swedish missionary Johannes Campanius during the 1640s and published with additions in 1702.[2] Campanius's vocabulary contains only 89 words but is sufficient to show that Susquehannock was a northern Iroquoian language closely related to those of the Five Nations.[3] Surviving remnants of the Susquehannock language include the river names Conestoga, Juniata, and Swatara.
