In English, you can have a sibling. In Swedish, it’s ett syskon. And in Norwegian, it’s et søsken. But in Danish, you can only have siblings in the plural form. At least according to Retskrivningsordbogen (lit. The Orthographical Dictionary), which establishes the official Danish orthography.
In Danish, ’siblings’ is only used in the plural. Some have started using ’en søsken’ for gender neutrality, but it’s not in the official dictionary.
