Language revitalisation is an attempt to halt or reverse the decline of a language, or to revive one that has fallen out of use. It usually works by getting children and adults to learn and use the language again, often through schooling and community programmes.
Key takeaways
- Revitalisation tries to stop or reverse a language's decline, or to revive an extinct one.
- Immersion settings for young children, such as Maori language nests, are among the best known methods.
- On our map, Welsh is rated threatened, Maori shifting and Hawaiian moribund by Glottolog.
- The map shows a status snapshot, not the effort behind it, so it cannot show whether a revival is working.
How revitalisation works
Language revitalisation is an attempt to halt or reverse the decline of a language, or to revive an extinct one. It is also called language revival or reversing language shift [1]. The central aim is to restore transmission: children and adults need to use the language, not just know about it.
Programmes differ, and researchers argue about which methods suit which situation. Immersion, where learners hear the language all day, is widely used, though one scholar cited on the topic argues it cannot revive an extinct or moribund language and prefers a master-apprentice approach, where a fluent elder works one to one with a learner [1]. Other tools include classes for adults, media in the language, and digital resources. The page on Hawaiian notes that it was added to the Duolingo platform in 2018, which widened access but drew questions about accuracy from some native speakers [1].
Success is hard to measure. Hebrew is the one revival on a large scale, and it helped that it survived as a liturgical language beforehand [2]. Cornish is a partial success: UNESCO moved it from extinct to critically endangered after about a century of effort [2].
An example from our data
Three languages on the map are often named in revitalisation stories. Hawaiian was displaced by English on six of the seven inhabited Hawaiian islands, and revival efforts, including immersion schools, have grown in recent decades [1]. On the map it is rated moribund with about 26,000 speakers (2010 United States Census, 2010), a figure that is approximate.
Maori in New Zealand was revived through language nests, where small children are raised in immersive settings [1]. It is rated shifting, with about 214,000 speakers (stats.govt.nz, 2023). Welsh is rated threatened, with about 724,000 speakers (Wikidata (unreferenced)). See the pages for Maori, Hawaiian and Welsh, and the overview in languages at risk.
The thing people get wrong
Many people expect a revived language to be the same as the one that was lost. In practice, a revived language often differs from earlier speech. The Hawaiian page notes a proposed distinction between "Neo-Hawaiian" and "Traditional Hawaiian", linked to heavy English influence [1]. Whether such differences matter, and who decides what counts as authentic, is something communities debate themselves.
A second mistake is to read a status on the map as a verdict on the effort. Glottolog's statuses are a snapshot taken from published surveys, so they may not yet reflect a recent turnaround, and the map has no data on programmes.
Frequently asked questions
Can a dead language come back?
Sometimes. Hebrew is the one large-scale case, and Cornish moved from extinct to critically endangered in UNESCO's ratings, but most revivals are smaller.
Which languages on this map are being revived?
The map does not record revival programmes. It shows Glottolog's endangerment status, for example Welsh as threatened and Hawaiian as moribund.
