Why the Icelandic language remains a living link to the island’s early days

Conservative grammar, a rich literary legacy and active preservation efforts have helped Icelandic resist the changes seen in other European languages.

Íslenska, or the Icelandic language, offers an unusual window into the medieval past of northern Europe. Carrying forward structures, sounds and words from its Viking-age origins, it remains the national language of Iceland, spoken today by about 390,000 people.

A language shaped by history and isolation

Icelandic belongs to the North Germanic branch of the Indo-European family. It is closest to the languages of the Faroe Islands and western Norway, and is descended directly from Old Norse, the language brought to Iceland mostly by settlers from western Norway in the 9th century. Over time, the Icelandic spoken by these settlers and their descendants slowly diverged from Norwegian, especially after about 1400, as isolated communities developed their own linguistic identity.

The sagas of Icelanders, written from the 12th century onward, are still accessible to modern speakers, a fact that is quite rare in world languages. This is due in large part to the conservative nature of written Icelandic, which has changed little since these early texts were first committed to vellum. Modern schoolchildren, with some training, can pick up sagas such as the Poetic Edda and read them much as they were written. Changes in pronunciation have been more significant, especially between the 12th and 16th centuries, but grammar and much vocabulary have remained remarkably stable.

Grammar, sound and vocabulary: holding onto old ways

Unlike most languages in Western Europe, Icelandic retains a highly inflected grammar, preserving four grammatical cases, nominative, accusative, dative and genitive, and three genders, with nouns and adjectives both declining. These features go beyond what is found even in German today. Many strong or irregular declensions are still in everyday use, which makes Icelandic grammar one of the most complex among living Germanic languages.

Phonetically, Icelandic has a system of stops that are all voiceless, with some pronounced with a breathy burst at the start of words and others with extra breath between sounds. The language also features unique sounds: for example, the letter ð (called ‘eth’) and þ (‘thorn’), both of which are relics of Old Norse. There are eight simple vowels and five diphthongs, with vowel length influenced by their position in a word.

One striking element of Icelandic culture is its commitment to language preservation. Loanwords from other languages are usually avoided in favour of coining new Icelandic terms based on older roots. A state-funded research institute, Árni Magnússon Institute for Icelandic Studies, safeguards medieval manuscripts, and the Icelandic Language Council, made up of experts from various institutions, advises on language policy.

Since 1995, November 16th, birthday of the 19th-century Icelandic poet Jónas Hallgrímsson, has been celebrated as Icelandic Language Day, underscoring national pride in linguistic heritage.

Beyond Iceland, around 8,000 Icelandic speakers live in Denmark, 5,000 in the United States and about 1,400 in Canada, mainly in Manitoba’s New Iceland area settled in the late 19th century.
