<p>What one do you enjoy more and do you have particular interests related to either Germanic or Slavic families? They’re really the only things you need to consider. Don’t take Russian if you think it’ll be more beneficial if your heart is with German.</p>
<p>Oh and German has huge international importance in Europe (especially the East) so dont think you’re confining yourself to Germany, Switzerland and Austria.</p>
<p>Gil, what use is there in a linguist learning Arabic if they’re intersted in North Germanic etymology? None. The field of Linguistics is as varied as there are languages. If the OP enjoys (and therefore far more likely to reach fluency) Russian or German its stupid to suggest that they should concentrate on another language, or another subject entirely.</p>

<p>Whilst that is true (to an extent), it isn’t practical for non-EU citizens. Majoring in a language and spending time studying abroad is really the best option in the OPs case. </p>

<p>Sorry to be blunt, but you think wrongly.</p>
