or Feodal (2 syl.) In Gothic odh means
“property,” hence odh-all (entire property); Flemish, udal.
By transposition we get all-ohd, whence our allodium
(absolute property claimed by the holders of fiefs); and by combining
the words fee and odh we get fee-odh, feodh, or feod (property given by way of fee for services conferred). (Pontoppidan.)
