alsýkn (ON) adj.

Completely reprieved; acquitted. Grg Vís 110 stipulates that certain types of outlaw could have his sentence ameliorated by dispatching other outlaws or by having someone do so on his behalf. The outlaw’s punishment was reduced for each outlaw killed up to three, at which point he became alsykn. A nominal form of the term (ON alsykna) appears once in the Staðarhólsbók version of Grg in the section on betrothals (cf. Grg tr. II:282–83). In one later usage from 1466 (DN X nr. 235) alsykn is employed as a synonym of ON sykn in the sense of ‘free, ordinary’ as opposed to a holiday.
