Linguistic body has relaxed rules on use of apostrophe to show possession, not traditionally correct in German
[G]uidelines issued by the body regulating the use of Standard High German orthography have clarified that the use of the punctuation mark colloquially known as the Deppenapostroph (“idiot’s apostrophe”) has become so widespread that it is permissible – as long as it separates the genitive ‘s’ within a proper name. [...] The Deppenapostroph is not to be confused with the English greengrocer’s apostrophe, when an apostrophe before an ‘s’ is mistakenly used to form the plural of a noun (“a kilo of potato’s”).
