      <p>Bør ordet <em>crew</em> inn i dei norske standardordbøkene? Korleis definerar vi <em>c-kjendis</em>, og korleis
        bøyar vi eigentleg <em>abaya</em> på nynorsk - er det fleire <em>abayaer</em> eller <em>abayaar</em>? Blir <em>en vegetar</em>
        framleis brukt som ein rettskrivingsvariant av <em>en vegetarianer</em> i bokmål? Og bør <em>tjuesesse</em> bli eit opplsagsord i Bokmålsordboka
        når ein tilsvarande ordartikklel allereie finst i Nynorskordboka?
      </p>
      <p>Slike spørsmål skal ei gruppe ordbokredaktørar ved UiB arbeide med i den mest omfattande innhaldsrevisjonen av Bokmålsordboka og Nynorskordboka
      på over 30 år.</p>
