landsmáli (ON) noun

The right of redemption, or preemption, of land. When sold, a condition could be placed upon land whereby the original seller was allowed to purchase it back when the land went on sale again, if he were willing to match the highest bid. These rights could be passed on to heirs (cf. Grg Lbþ 192).
