  Origins and meanings of name
  The county bears the name of three historic counties of Hungary, each of them was centered around a castle.
  Borsod is named after the castle to which it belonged. The castle was possibly named after its first steward, Bors (in old Hungarian language the -d suffix was a derivation suffix for place names, thus the name Borsod means 'place belonging to Bors.') The name Bors itself is of Hungarian origin, derived from the Turkish loan word bors, which means 'black pepper / peppercorn' or a Slavic personal name Bor(i)š, Borša. The castle itself was a motte castle, and stood near modern-day Edelény.
  Abaúj is a shortened form of the name of its castle, Abaújvár. The Aba portion refers to the Aba clan which ruled the area in the Middle Ages, while új vár means 'new castle.' The castle stood near the village of Abaújvár.
