An Etymological Dictionary of the German Language/Sod

by Friedrich Kluge

Sod, m., usually Sotbrennen, ‘heartburn,’ from the equiv. MidHG. sôt (d), m. and n., which lit. means ‘bubbling, boiling,’ a derivative of MidHG. sieden. Hence ModHG. Sod, signifying ‘broth, well,’ as well as the local name Soden.
