A gord is a medieval Slavonic fortified settlement, also occasionally known as a burgwall or Slavic burgwall after the German term for such sites. The ancient peoples were known for building wooden fortified settlements. The reconstructed Centum-satem isogloss word for such a settlement is g'herdh, gordъ, related to the Germanic *gard and *gart (as in Stuttgart etc.). This Proto-Slavic word (*gordъ) for town or city, later differentiated into grad (Cyrillic: град), gard, gorod (Cyrillic: город), etc.
