Samuel Gyarmathi's Affinitas linguae hungaricae cum linguis fennicae originis grammatice demonstrata (Gottingen 1799) was received as a distinguished work of scholarship in its own days, and its historical importance has been fully recognized ever since. This volume provides an English translation of the entire Latin text, including the Latin glosses of the original (with the exception of zoological and botanical terms, and a few passages where specific reference is made to Latin grammar). This translation includes two additions to the text of Affinitas as reprinted in the Indiana University series: Appendix III, a letter to Gyarmathi by A. L. von Schotzler, and a number of notes in the author's own hand, found in his copy of the work (now held in the Library of the Lycee of Zalău). The translator's Preface provides an introduction to the work and an overview of Gyarmathi's life.
