Breton (Brezhoneg)

1. Introduction & endangerment status

Breton (Brezhoneg) is an Insular Celtic language of the Southwestern Brittonic group — the only Celtic language whose homeland is on the European mainland. It is a very close relative of Cornish and a cousin of Welsh, brought to the Armorican peninsula (modern Brittany / Breizh, in north-west France) by migrants from Britain in the early medieval period. It is spoken chiefly in western (Lower) Brittany.¹² Confidence: High.

Breton's situation is grave: it has fallen from more than a million speakers around 1950 to figures variously estimated between about 107,000 (2024) and 207,000 (a 2018 survey), with UNESCO citing roughly 250,000. Crucially, most remaining traditional speakers are elderly — the average age is high — and the language receives little institutional support from the French state. UNESCO classifies Breton as 'severely endangered'.²³ Confidence: High.

Against this decline stands an active revival: the Diwan network of Breton-immersion schools (founded 1977), bilingual streams in state and Catholic schools, the standard-orthography movement, media such as radio and the magazine and online presence of the language movement, and the cultural office Ofis Publik ar Brezhoneg. This learner infrastructure makes Breton, despite its endangerment, an accessible language to study.²³ Confidence: High.

This guide rises through the eight CEFR sub-levels, from the alphabet (A1.1) toward reading Breton media and literature and joining the language community (B2.2). Each level is marked with a visible heading.

Breton is written in the Latin alphabet. Its most distinctive letter combination is c'h, a single sound /x/ (like 'ch' in 'loch'), kept separate from the digraph ch /ʃ/ ('sh'). The letter ñ marks nasalisation of a preceding vowel rather than a separate consonant. The dominant modern orthography is the unified peurunvan ('completely unified', 1941), though other spelling systems exist. Stress normally falls on the penultimate syllable.¹ Confidence: High.

A first set of greetings and polite expressions opens almost any conversation with a fellow learner or community member. All forms below are drawn from the cited reference materials.¹

The cardinal numerals one to ten are listed below, with twenty and one hundred. Like the other Celtic languages, the traditional higher numbers use a vigesimal (base-twenty) system.⁴

Breton word order is famously flexible and information-driven: the element the speaker wants to highlight is placed first, followed by the conjugated verb (a verb-second / fronting pattern), so the same idea can begin with the subject, the object, or an adverb. There is a definite article (an / ar / al) and an indefinite article (un / ur / ul), unusually among the Celtic languages. Nouns have two genders.¹² Confidence: High.

A starter set of everyday words — family, common nouns and colours — for first sentences:

The signature Celtic feature is initial mutation: the first consonant of a word changes with grammar. Breton has four mutation types (soft/lenition, spirant, hard and mixed). So tad 'father' becomes ma zad 'my father', and Breizh 'Brittany' can appear mutated after certain words. Mastering the four mutations and their triggers is the central intermediate task.¹² Confidence: High.

Breton conjugates verbs for tense and person, but a very common everyday pattern uses the auxiliary ober 'to do' plus a verb-noun (e.g. Komz a ran 'I speak', literally 'speaking I-do'), and the verb bezañ 'to be' has distinct forms for habitual versus situational meaning. As in its relatives, there is rich use of conjugated prepositions. Breton keeps singular te and plural/polite c'hwi for 'you'.¹² Confidence: High.

Advanced competence means handling the major dialect division — the three KLT dialects of Léon, Tregor and Kernev (Cornouaille) versus the rather different Gwenedeg (Vannetais) of the south-east — and the gap between traditional native speech and the more standardised 'neo-Breton' of the school and revival movement. Centuries inside French-speaking France have left heavy French borrowing; recognising it helps keep inherited Celtic structure clear.¹² Confidence: High.

At the top of the ladder the community is the classroom. Breton sustains the Diwan immersion schools, radio stations and a bilingual broadcast presence, an annual festival culture (the festoù-noz dance gatherings, recognised by UNESCO as intangible heritage), a strong song and music scene, and a literary tradition from the 19th-century Barzaz Breiz ballad collection to modern prose and poetry. Reading goals at this level include Breton news, fiction and song lyrics.¹² Confidence: High.

Revitalization & preservation

Breton's revival runs against strong headwinds: France's centralised language policy gives it little official status, and most native speakers are elderly. Yet the Diwan immersion-school network (since 1977), bilingual streams in other schools, the unified peurunvan orthography, the cultural office Ofis Publik ar Brezhoneg, radio and online media, and a vigorous music and festoù-noz festival culture all sustain new learners. The continuing challenge, reflected in UNESCO's 'severely endangered' label, is bridging the generational gap between ageing native speakers and young 'neo-Breton' learners before traditional transmission is lost.²³
