- að gleyma einhverju = to forget something
- reglustikunni is the dative singular definite form of reglustika.
A useful comparison:
- reglustika = a ruler
- reglustikuna = the ruler (accusative)
- reglustikunni = the ruler (dative)
With gleyma, Icelandic wants the dative form, so reglustikunni is the correct choice.
