Yes, if you spot ß, that&#x27;s a dead giveaway for German. You can&#x27;t really rely on it alone for identification however because it&#x27;s not that frequent (or rather, it&#x27;s very inconsistent – German can run for paragraphs without a single ß only to make up for it with five of them in a single sentence). It&#x27;s also not used at all in Swiss German.<p>Another near-certain giveaway is that all nouns in German are capitalised. The only other language that does that and uses the Latin alphabet is Luxembourgish, and you&#x27;re probably not looking at that.
