Passage: English and Danish are compulsory subjects in the school curriculum. English is widely understood and spoken, while basic to moderate knowledge of Danish is common mainly among the older generations. Polish is mostly spoken by the local Polish community (the largest minority of Iceland), and Danish is mostly spoken in a way largely comprehensible to Swedes and Norwegians—it is often referred to as skandinavíska (i. e. Scandinavian) in Iceland.Rather than using family names, as is the usual custom in most Western nations, Icelanders carry patronymic or matronymic surnames, patronyms being far more commonly practiced. Patronymic last names are based on the first name of the father, while matronymic names are based on the first name of the mother. These follow the person's given name, e.g. Elísabet Jónsdóttir ("Elísabet, Jón's daughter" (Jón, being the father)) or Ólafur Katrínarson ("Ólafur, Katrín's son" (Katrín being the mother)). Consequently, Icelanders refer to one another by their given name, and the Icelandic telephone directory is listed alphabetically by first name rather than by surname. All new names must be approved by the Icelandic Naming Committee.
