tvist ‘silent’: Earlier eds emend to tyst to retain the aðalhending (cf. ODan. tyst; AEW: tvistr), and it is quite likely that Sigvatr could have used an Old East Norse form since he had just spent a long time in Sweden (1031-5; see ÍF 28, 17-18). For another, possibly Old East Norse form, see st. 10/4 below. Skj B translates the word as tvedragt ‘discord, division’ (so also LP: tvistr 1), but it is otherwise unattested in that meaning.
