Unveiling Icelandic speech: the legacy of the First Grammatical Treatise

Composed in 12th-century Iceland, the First Grammatical Treatise stands as a pioneering record in the study and standardisation of Old Norse language, reflecting both Latin learning and native poetic insight.

In the middle of the 12th century, an Icelandic scholar embarked on a linguistic project that would leave an enduring mark on the history of language studies. Known as the First Grammatical Treatise, or “Fyrsta málfræðiritgerðin” in Icelandic, this work explored the sounds and structure of Old Norse, the language then spoken across Iceland. Its author remains anonymous, often simply called the “First Grammarian,” yet the treatise offers a close look at the intellectual world of medieval Iceland.

Bound within the Codex Wormianus manuscript, this treatise is not only the earliest known Icelandic work on grammar but also represents one of the first linguistic compositions written in any North Germanic tongue. Its focus goes well beyond cataloguing words, delving deep into the phonological underpinnings of language, a field that would not become formalised until many centuries later.

A quest to adapt the Latin alphabet

At a time when the older Runic script was still in some use for inscriptions, the First Grammarian sought to create an alphabet derived from Latin letters, tailored to suit the requirements of writing down Icelandic speech. He proposed unique signs, such as þ (thorn) from the runes, and introduced diacritical marks to signify vowel length and nasalisation. Long vowels were to be marked with an acute accent, and nasal vowels indicated with a dot.

His suggested system even included a character called ‘eng’ (ꞡ) for specific nasal sounds, and distinctions like small capital letters to identify double consonants. While some of these innovations did not persist, features like the use of þ and diacritics for vowels influenced Icelandic spelling practices for generations.

Systematic study and poetic roots

What sets the treatise apart in linguistic history is its analytical approach. Drawing on techniques centuries ahead of their time, the author demonstrated the concept of “minimal pairs”, pairs of words that differ in just one sound, revealing the elements that make words distinct. Through this methodology, he identified a rich inventory of vowels and pointed out the existence of nasal vowel sounds, knowledge that would otherwise have been lost.

Besides his linguistic methodology, the First Grammarian’s background suggests influences from both Latin scholasticism and local poetic tradition. His vocabulary and references indicate he was deeply versed in Latin learning, possibly linked to monasteries like Þingeyrar in northern Iceland. At the same time, he drew on the local oral literature, with examples alluding to legendary Norse figures.

Though the treatise did not result in a long-lived standard for spelling or pronunciation, it remains a remarkable snapshot of the language just prior to the saga-writing age. The attempt to codify the vernacular reveals an Icelandic society wrestling with questions of identity, communication, and cultural preservation, a process as relevant now as it was in the Middle Ages.
