An Etymological Dictionary of the German Language/Annotated/Eintracht

by Friedrich Kluge

Eintracht, feminine, ‘concord, harmony, agreement,’ from the equivalent late Middle High German eintraht, feminine, which, however, belongs, as a Middle German word, to treffen; hence Middle German cht for ft. Old High German preserves the correct form eintraft, ‘simple.’ Compare Zwietracht.
