Ar Ir Er Verbs

How to actually parse Ar Ir Er Verbs in Breton without losing your mind

Most people coming to Breton from French or English hit a wall pretty fast when they reach the verbal noun system. The Ar/Ir/Er construction isn't some advanced topic. It shows up in the first week of any decent textbook. But the way it's taught is usually so abstract that students memorize patterns they can't actually apply. I spent about six months wrestling with this before it just clicked. So here's how I ended up handling it. The core idea is straightforward: Breton uses verbal nouns where other languages use infinitives, and those verbal nouns need prepositions to link to them. The three main prepositions you need to know are ar, ir, and er. They roughly correspond to different grammatical contexts. "Ar" marks the definite verbal noun. "Ir" is the contracted form of "en devo" and functions as a future/intent marker. "Er" is the contraction of "en eus" and marks possession or the third-person singular present.

Understanding Ar Ir Er Verbs in Practice

I used to teach these as separate rules. That doesn't work. They're better understood as parts of the same system built around the preposition "en" meaning "in" plus the conjugated forms of the verb "bezañ" (to be). When you see "er," it's "en" + "eus." When you see "ir," it's "en" + "do." When you see "ar," it's just the article before a verbal noun. The relationship between them is structural, not arbitrary. Here's the practical breakdown. "Ar gwelet" means "the seeing" or "to see" in a general sense. It's the verbal noun with the definite article. You use it when the action itself is the topic. "Izelat" or "da lizera" would be a different construction entirely. "Eñ a zo o lenn" becomes "Er bed" when contracted. This gets confusing because the spelling changes based on dialect. The Vannetais dialect handles these contractions differently than the Trevor dialect. Pick one and stick with it until you're comfortable. Mixing them will make your writing look inconsistent. A common mistake beginners make is treating "ir" as just another preposition. It's not. It carries modal meaning. It implies intention or future orientation. If someone says "Emañ o tont" they're describing an ongoing action. If they say "En deus da vont" the "er" form shifts to something else entirely. This is where my own struggle came in. I kept confusing the possessive construction with the modal one.

My workaround was to stop trying to translate word-for-word and start thinking in terms of sentence slots. Every Breton clause has a position for the verb, a position for the subject marker, and a position for the verbal noun complement. Once I mapped it that way, the Ar/Ir/Er patterns fell into place. I drew a simple table with columns for declarative, negative, and interrogative forms and filled it in with examples from actual texts instead of textbook exercises. Textbook examples are sanitized. Real texts show you where the contractions actually break down. One edge case I ran into regularly: the interaction between "er" and nasal mutation. When "en eus" contracts to "er" before a vowel-initial verbal noun, the mutation doesn't always apply consistently across sources. Some grammars list it as optional. In practice, most native speakers I've spoken with do mutate. I learned to expect it and flag it when it was missing. That saved me from second-guessing every sentence I read. Another thing nobody really emphasizes: the negative form. "N'en deus ket" contracts to "N'er ket" in rapid speech. The spelling in formal written Breton sometimes keeps the full form. If you're studying from a textbook that only shows the formal version, you'll be confused when you hear actual conversations. There's no universal standard here. The Académie de la Langue Breonne has tried to standardize, but daily usage varies enough that you need exposure to both registers.

For anyone wanting to practice, the best resource I found was the online dictionary at Geriadur.net. It lists verbal nouns with their prepositional constructions. The Frenger project at the University of Kent also has good material, though it's more academic than practical. I also recommend the app "Brezhoneg" by Kontad. It has exercises specifically on the Ar/Ir/Er system and gives you immediate feedback. The free tier covers the basics. The paid tier includes dialectal variants which is useful if you're serious about this. The real difficulty isn't memorizing the forms. It's recognizing when each one is appropriate in context. I'd say it takes about two to three months of regular practice to get comfortable. Not fluent. Just comfortable enough that you stop translating from French in your head every time you encounter one. After that, it becomes automatic. If you're starting out, don't try to learn all three at once. Pick "ar" first. It's the simplest and most common. Spend two weeks working exclusively with verbal nouns preceded by "ar." Once that feels normal, add "er." Then tackle "ir." Each one opens a new set of sentence patterns. Adding them too quickly just creates interference and you end up using the wrong form in every sentence anyway.
