Endangered language
An endangered language is one at high risk of extinction due to declining speaker numbers and interrupted intergenerational transmission, where younger generations increasingly adopt dominant languages instead.[1][2] This phenomenon occurs when speakers voluntarily shift to more economically or socially advantageous tongues, often in response to globalization, urbanization, and assimilation pressures, rather than solely through coercive external forces.[3][4] Of the approximately 7,100 living languages worldwide, Ethnologue classifies over 3,100—roughly 44%—as endangered, with vulnerability assessed via factors such as total speakers (often under 1,000), proportion of fluent elderly speakers, restricted usage domains, and absence of written materials or institutional support.[5][6] SIL International emphasizes that endangerment intensifies when languages cease serving vital community functions, leading to rapid decline without active maintenance.[7] Peer-reviewed analyses identify small initial speaker bases and proximity to linguistically diverse but dominant neighbors as key predictors, with projections indicating potential tripling of losses within decades absent intervention.[3] Preservation efforts focus on documentation through fieldwork and digital archiving, alongside revitalization via education and community programs, though success varies and often hinges on speakers' intrinsic motivation rather than top-down policies.[8] Controversies arise over the prioritization of certain languages, with critics noting that natural selection of tongues mirrors efficiency in communication and adaptation, potentially rendering widespread alarmism—prevalent in academic circles—more ideologically driven than empirically urgent.[9] Empirical data underscores that while each loss erodes unique cognitive and ecological knowledge repositories, language consolidation has historically enriched surviving idioms without halting human innovation.[10]Definition and Assessment
Criteria for endangerment
The primary framework for assessing language endangerment is UNESCO's Language Vitality and Endangerment evaluation, developed in 2003 by an international group of linguists, which identifies nine interrelated factors to determine a language's vitality or risk of extinction.[2] These factors emphasize empirical indicators of usage and transmission rather than arbitrary thresholds, including intergenerational transmission (whether children learn the language from parents), absolute number of speakers, proportion of speakers within the ethnic population, shifts in domains of use (e.g., home, work, education), adaptation to new media, availability of educational materials, governmental policies supporting the language, and community attitudes toward its preservation.[2] Languages are classified into degrees of endangerment—vulnerable (most children speak it but with restrictions), definitely endangered (children no longer learn it as a mother tongue), severely endangered (spoken only by grandparents and older generations), or critically endangered (few speakers remain, mostly elderly)—based on the predominance of negative trends across these factors, with extinction occurring when no speakers survive.[2] An alternative scale, the Expanded Graded Intergenerational Disruption Scale (EGIDS) used by SIL International and Ethnologue, builds on Joshua Fishman's 1991 Graded Intergenerational Disruption Scale (GIDS) by incorporating 13 levels from institutional support (levels 0-4, assessing written use, literacy, and official status) to intergenerational transmission (levels 6a-6b, evaluating home and community proficiency) and eventual loss (levels 7-10, from dormant to extinct).[11] Endangerment is gauged primarily through disruption in transmission—e.g., a language at EGIDS level 6a is used conversationally by all generations but ceasing in organized settings, while level 7 indicates only elders speak it fluently—drawing on speaker surveys, census data, and fieldwork to quantify vitality against dominant languages.[11] This scale prioritizes causal mechanisms like shift to vehicular languages, with viability thresholds varying by context (e.g., fewer than 50 speakers often signals near-extinction in isolated communities).[12] Both frameworks rely on verifiable data such as demographic surveys and linguistic documentation, though challenges arise from inconsistent reporting and subjective attitudes; for instance, low speaker numbers alone do not suffice if transmission remains robust, as seen in some minority languages sustained by cultural isolation.[2][11] Assessments often cross-validate multiple factors to avoid over-reliance on any single metric, ensuring classifications reflect ongoing decline rather than static snapshots.[13]Scales and classifications
The degree of endangerment for languages is assessed using standardized scales that primarily evaluate intergenerational transmission, speaker demographics, and institutional support. UNESCO's framework, detailed in its 2003 expert report "Language Vitality and Endangerment," classifies languages into six categories based on the proportion of speakers relative to the ethnic population and the continuity of transmission across generations.[2] This scale emphasizes empirical indicators such as the age of the youngest fluent speakers and the language's role in education or media, though it relies on self-reported data from field linguists, which can introduce variability in assessments.[2]| Degree of Endangerment | Description |
|---|---|
| Safe | Language spoken by all generations with uninterrupted intergenerational transmission.[2] |
| Vulnerable | Most children speak the language, but it may be restricted in domains like formal education.[2] |
| Definitely Endangered | Children no longer learn the language as mother tongue in the home.[2] |
| Severely Endangered | Spoken only by grandparents and older generations; not passed to children.[2] |
| Critically Endangered | Few speakers remain, mostly elderly, with no transmission to younger generations.[2] |
| Extinct | No speakers left, or only revitalization efforts without fluent users.[2] |
