holmgang
In Norse and Icelandic culture, a duel to the death.
countable, uncountable
A man could no longer be challenged for his lands or his women-folk, since the only result of holmgang which the law would allow, apart from wounds or death, was a claim for the payment of the agreed stakes.
Where it comes from
