&gt; That&#x27;s not precisely true (...) Everyone here speaks Hochdeutsch too<p>Linguistically, Swiss speak Hochdeutsch even when they speak Swiss German(!) Which a lot of Germans of Germany don&#x27;t when they speak their dialect.<p>So your argument is quite wrong and certainly not &quot;precise.&quot;<p>The German speaking people all have local dialects and have to adapt when they move. But these are all &quot;just&quot; dialects. Ask Germans, they aren&#x27;t surprised when they have to get accustomed. Look at the map here:<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;German_dialects" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;German_dialects</a><p>Note that all &quot;upper&quot; German regions are actually where &quot;<i>Hochdeutsch</i>&quot; (<i>Upper German</i>) comes from. Yes, &quot;up&quot; is on the South, down on the map. And the area includes Switzerland.<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Swiss_German" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Swiss_German</a><p>&quot;Swiss German (German: Schweizerdeutsch, Alemannic German: Schwyzerdütsch, Schwiizertüütsch, Schwizertitsch[note 1]) refers to any of the Alemannic dialects spoken in Switzerland and in some Alpine communities in Northern Italy.&quot; OK, let&#x27;s check Alemannic:<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Alemannic_German" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Alemannic_German</a><p>&quot;Alemannic is a group of dialects of the <i>Upper German</i> branch of the Germanic language family.&quot;<p>Finally, it follows that Swiss German dialects are actually all branches of &quot;<i>Hochdeutsch</i>&quot; family(!) They are just not the same as today&#x27;s &quot;standard German.&quot; Which is what people you communicate to probably mean when they say &quot;Hochdeutsch&quot;:<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Standard_German" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Standard_German</a><p>See also DominikR&#x27;s post here. He being an Austrian, his dialect also from the same &quot;Hochdeutsch&quot; family of dialects, wouldn&#x27;t feel as an &quot;immigrant&quot; in Switzerland.
