Yes, We Speak English
Icelandic has been spoken in Iceland since the country was settled in the 9th century and has changed little since then. It is mostly the language that the Nordic people spoke in the Middle Ages throughout the Nordic countries as well as within certain regions of England, Ireland, Scotland, along with the Shetland Islands, the Orkney Islands and the Hebrides, some parts of France and Russia and even as far south as Constantinople.
Despite the centuries of foreign rule, the Icelandic language has not been greatly influenced and the difference between old and modern Icelandic is insignificant. Icelanders can still read and understand ancient Icelandic texts, such as the Icelandic Sagas, without difficulty.
Icelandic has been rated as one of the hardest languages to learn as a result of the archaic vocabulary and complex grammar. But don't worry! English is taught as a second language in Iceland and almost every Icelander speaks the language fluently. And more so, most Icelanders speak several other languages including Danish, German, Spanish and French and welcome the opportunity to practice their language skills.
Hope to see you soon in Reykjavík.
