Frequently Asked Questions
Where can I learn Gaulish?
The Gaulish language has received relatively little attention outside of scholarly circles and, as such, resources on Gaulish tend to be limited to research papers and scholarly articles. Furthermore, the vast majority of work on Gaulish is published in French with little English material available. Check out our resources list for some materials to get started.
Gaulish vs Gallic vs Gaelic?
The terms Gaulish and Gallic can be used more or less interchangeably.
Gallic is derived from the Latin word Galli, which was a term Roman writers used in reference to the Celtic peoples who inhabited central and western continental Europe. Hence why Julius Caesar's memoirs from the Roman conquest of Gaul are called the Commentarii de Bello Gallico. It likely came from the Greek word Galatai which was likely derived from a Celtic word.
Gaul or Gaulish are terms both derived from the Proto-Germanic term Walhaz which literally meant "foreigner". The ancient Germans used Walhaz generically to refer to any people who didn't speak a Germanic language including the Celts and Romans. When the Franks conquered the area of modern-France, they called it Walha(land) while later evolved into Waulle, then Gaule, finally ending in the modern English Gaul.
Gael or Gaelic come from the Irish language in which it simply means "Irishman". The Irish language is also often called Irish Gaelic or simply Gaelic. It evolved from the old Irish word Goídel which likely comes from the Proto-Celtic word *weidelos meaning "savage, woodsman". It is etymologically unrelated to the term Gaul and there is no evidence connecting it to the term Galatai.
Are there surviving examples of Gaulish?
Yes. Archaeologists have discovered hundreds of inscriptions in the Gaulish language written in both the Greek and Latin scripts although these inscriptions are often fragmentary and many are only a sentence long. The Recueil informatisé des inscriptions gauloises (RIIG) or "Computerized Collection of Gaulish Inscriptions" is a French project seeking to compile all Gaulish inscriptions into one publicly available online database.
While the Gauls were a literate people, they didn’t have the kind of literary tradition that produced large books and manuscripts as the Romans and Greeks did. The Gauls tended to use writing for things like funerary inscriptions, dedications to gods, marking ownership of property, curses and other magical incantations, advertisements for businesses, and for decorative purposes. Because of this, our understanding of Gaulish grammar (especially verbs and syntax) is extremely limited although we have a fairly sizable lexicon.[1]
Why do I see letters with a strikethrough in some Gaulish words? (ss, dd, etc)
They’re all various ways of representing the tau gallicum or “Gaulish tau” (Ꟈ), a unique character that appears in some Gaulish inscriptions. It’s believed by most linguists to have represented a /ts/ or /st/ sound although some also think it might have been [θ] (the English /th/ sound)[2]
Some common methods include:
- double unbarred s (ss)
- double barred s (
ss) - double unbarred d (dd)
- double barred d (
dd) - barred d + s (
ds) - eth (ð)
- double eth (ðð)
It’s important to always check the orthographic rules of the Gaulish dictionary or grammar book you use to see how the author chose to represent it (if at all! Some just write ts or st.)
When did Gaulish go extinct?
Most historians place the extinction date for Gaulish sometime in the late 6th Century CE because this is when the last probable attestations and inscriptions of Gaulish being spoken have been dated. It’s possible that it survived afterward into the 7th century and a few scholars have argued for dates as late as the 9th or 10th centuries but the former claim is unproven while the latter is controversial.
It’s also important to understand that the decline of Gaulish wasn’t as simple as Gaulish speakers switching to Latin. As Latin saw greater usage in Gaul, a unique regional dialect with considerable Gaulish influence emerged among the increasingly bilingual populace and in later Roman history, it becomes difficult to distinguish Gaulish from this Gallic Latin vernacular both in inscriptions and in references by Roman writers.[3]
What is “Reconstructed Gaulish”?
While our understanding of Gaulish is limited by our few available sources, some linguists have attempted to reconstruct its unknown features by analyzing how the Proto-Celtic language evolved into Gaulish and making comparisons to other languages in the Celtic family. These reconstructions are highly speculative but offer examples of what Gaulish may have looked like.
Two well-known reconstructed Gaulish grammars are Gallicâ Iextis Toaduissiouibi by Gérard Poitrenaud (available only in French) and Yextis Keltikā by Olivier Piqueron (available in French and English), the former of which has a strong online following on Facebook and on reddit at /r/Gallica_Iextis.
What is “Modern Gaulish”?
Modern Gaulish or “Galáthach hAthevíu” is a constructed language intended to resemble what Gaulish might hypothetically have looked like if it had survived to modern times, taking inspiration from possible trends in the evolution of Gaulish found in the literary record as well as by studying how other surviving Celtic languages have evolved. While not the only project of its nature, it’s by-far the most popular and its not uncommon to find fans of the project in online spaces dedicated to Gaulish.
