Middle Breton appears in the <em>Catholicon</em>, a Breton-Latin-French dictionary published in 1499 and attributed to Jean Lagadeuc. A number of texts that date from the 15th through 17th centuries use Late Middle Breton, mostly in the form of elaborate poetry that exhibits a prosody akin to that of <a class="md-dictionary-link md-dictionary-tt-off mw" data-term="medieval" href="https://www.merriam-webster.com/dictionary/medieval" data-type="MW">medieval</a> Welsh poetry.

The dictionary had little significance for spoken Breton, however. Religious publications, which were nearer everyday speech, later flourished in the four Breton-speaking bishoprics of Brittany. The standards for written Breton developed separately in each, and the differences that subsequently emerged contributed to the theory that there existed four Breton <a class="md-dictionary-link md-dictionary-tt-off mw" data-term="dialects" href="https://www.merriam-webster.com/dictionary/dialects" data-type="MW">dialects</a>, each named for those bishoprics: Kerne, Leon, Treger, and Gwened (in French, Cornouaille, Léon, Tréguier, and <a href="https://www.britannica.com/place/Vannes" class="md-crosslink autoxref " data-show-preview="true">Vannes</a>, respectively). In fact, only Gwened differs significantly from the others, through a shift in stress accent and vowel aperture. Much energy was devoted during the 18th and 19th centuries to establishing a single written norm for Breton, especially after Jean-François Le Gonidec published a grammar (1807). He also published a Breton dictionary in 1821. But an unrelenting eradication policy <a class="md-dictionary-link md-dictionary-tt-off mw" data-term="implemented" href="https://www.merriam-webster.com/dictionary/implemented" data-type="MW">implemented</a> from the mid-19th century and into the 20th wrought havoc on Breton. No language census was ever taken. In 1928, after carrying out a survey, the scholar Roparz Hemon put at 1.2 million the number of people using Breton as their daily means of <a href="https://www.britannica.com/topic/communication" class="md-crosslink autoxref " data-show-preview="true">communication</a>.</p><div class="one-good-fact-module"> </div><span class="marker MOD4 mod-inline"></span><span class="marker PREMOD5 mod-inline"></span><p class="topic-paragraph">At the turn of the 21st century an estimated 500,000 people could understand and speak the language, and <a href="https://www.britannica.com/topic/public-opinion" class="md-crosslink autoxref " data-show-preview="true">public opinion</a> in Brittany strongly favoured the language. A Breton-language school system began to develop at that time, and bilingual education emerged in state-run and Roman Catholic primary schools. Adult education in Breton also expanded. Supporters of the language were <a class="md-dictionary-link md-dictionary-tt-off eb" data-term="optimistic" href="https://www.britannica.com/dictionary/optimistic" data-type="EB">optimistic</a> that it was being built into a modern, up-to-date, urban language: a unified spelling system had been developed, and the language was used on private and state-funded radio and television networks as well as in films.</p><span class="marker MOD5 mod-inline"></span></section> <span class="md-signature"><a href="/contributor/Per-Denez/5126">Per Denez</a></span> <span class="marker end-of-content"></span><span class="marker after-article"></span></div> <div id="chatbot-root"></div> </div> </div> </div> <div class="ai-dialog-placeholder"></div> </div> </div> <aside class="col-md-da-320"></aside> </div> </div> </div> </div> </article></div> </div></div> </div> </main> <div id="md-footer"></div> <noscript><iframe src="//www.googletagmanager.com/ns.html?id=GTM-5W6NC8" height="0" width="0" style="display:none;visibility:hidden"></iframe></noscript> <script type="text/javascript" id="_informizely_script_tag"> var IzWidget = IzWidget || {}; (function (d) { var scriptElement = d.createElement('script'); scriptElement.type = 'text/javascript'; scriptElement.async = true; scriptElement.src = "https://insitez.blob.core.windows.net/site/f780f33e-a610-4ac2-af81-3eb184037547.js"; var node = d.getElementById('_informizely_script_tag'); node.parentNode.insertBefore(scriptElement, node); } )(document); </script>  <script> window.ap3c = window.ap3c || {}; var ap3c = window.ap3c; ap3c.cmd = ap3c.cmd || []; ap3c.cmd.push(function() { ap3c.init('ZO4siT4cLwnykPnzZWJtd3Byb2Q', 'https://engage.email.britannica.com/'); ap3c.track({v: 0}); }); ap3c.activity = function(act) { ap3c.act = (ap3c.act || []); ap3c.act.push(act); }; var s, t; s = document.createElement('script'); s.type = 'text/javascript'; s.src = "https://engage.email.britannica.com/app.js"; t = document.getElementsByTagName('script')[0]; t.parentNode.insertBefore(s, t); </script> <script class="marketing-page-info" type="application/json"> {"pageType":"Topic","templateName":"DESKTOP","pageNumber":1,"pagesTotal":1,"pageId":78972,"pageLength":502,"initialLoad":true,"lastPageOfScroll":false} </script> <script class="marketing-content-info" type="application/json"> [] </script> <script src="https://cdn.britannica.com/mendel-resources/3-130/js/libs/jquery-3.5.0.min.js?v=3.130.14"></script> <script type="text/javascript" data-type="Init Mendel Code Splitting"> (function() { $.ajax({ dataType: 'script', cache: true, url: 'https://cdn.britannica.com/mendel-resources/3-130/dist/topic-page.js?v=3.130.14' }); })(); </script> <script class="analytics-metadata" type="application/json"> {"leg":"D","adLeg":"D","userType":"ANONYMOUS","pageType":"Topic","pageSubtype":null,"articleTemplateType":"MEDIUM","gisted":false,"pageNumber":1,"hasSummarizeButton":false,"hasAskButton":false} </script> <script type="text/javascript"> EBStat={accountId:-1,hostnameOverride:'webstats.eb.com',domain:'www.britannica.com', json:''}; </script> <script type="text/javascript"> ( function() { $.ajax( { dataType: 'script', cache: true, url: '//www.britannica.com/webstats/mendelstats.js?v=1' } ) .done( function() { try {writeStat(null,EBStat);} catch(err){} } ); })(); </script> <div id="bc-fixed-dialogue"></div> </body> </html>
