The language in Iceland

Icelandic is the official language. It is the ancient tongue of the Vikings and has changed remarkably little during the eleven centuries since the country was first settled, mainly due to the isolation of the island. Even to day Icelanders are able to read the old Sagas without any special training.
In Iceland we use patronyms rather than surnames. If, for example, John has a son named ,Peter, the son’s name is Peter Johns-son. If John has a daughter whom he names Margret, she becomes Margret Johns-daughter. Members of the same family can therefore have different “last names”.
