[3] skaltattu (2nd pers. sg. pres. indic.) ‘you must not’: Skallattu (so H, F; skalattu Hr) ‘you must not’ has been emended to skaltattu (i.e. skalt-at-þú lit. ‘must-not-you’). The metre requires a long syllable in position 2, and the correct form of the 2nd pers. sg. pres. indic. of the verb skulu ‘must’ is skalt.
