Friedrich Kluge, An Etymological Dictionary of the German Language (1891)
“ This implied wealth of pre-historic terms for degrees of kinship can be only understood by us as existing at a time when our ancestors lived together in clans as shepherds and nomads. When with the changing years the more fully developed relations of kinship lost the old inherited terms, how seldom have alien designations attempted to oust the native words, and how seldom with success! ”
