Chad has two official languages, Arabic and French,[1]: 575  and Ethnologue reports over 120 indigenous languages in the country.[2] Due to governmental bilingualism, inter-ethnic marriages, and language contact, most Chadians are multilingual.[1]: 581 

Official languages

The co-official languages of Chad, French and Arabic, reflect Chad's complex sociolinguistic history where indigenous people and languages coexist with two different waves of colonization.[1]: 575 

Arabic took hold following 16th century Arab migrations from Sudan, Nubia, and possibly through Trans-Saharan trade routes. A vernacular version of Arabic, Chadian Arabic, is a lingua franca and the language of commerce, spoken by approximately 60% of the population.[3]

France gained control of Chad during the early 20th century, and their colonial policies focused on spreading French as the primary language in Chad. A 1924 letter from the governor general of French Chad declared: "The spread of French is a necessity [...] The native is only allowed to present his/her requests in French." After Chad gained independence in 1960, French was retained by the new government as the official language, in part because it functioned as a neutral choice, rather than having to elevate one indigenous language over another.[1]: 576 

Arabic joined French as a co-official language in 1978, as part of a deal ending the Chadian Civil War by increasing northern Chadians' role in government.[4] French remains the dominant language in many workplaces, schools, and administrative institutions. A 2022 analysis found that about 75% of administrative institutions spoke exclusively in French, and a further 20% spoke French and Arabic.[1]: 577 [5]: 7 

Non-official languages

[edit]

The language with the most first-language speakers in Chad is likely Ngambay, which has an estimated one million speakers.[6] Ngambay is used as a commercial and inter-ethnic bridge language in Southern Chad and in the capital, N'Djamena.[1]: 587 

Many of major indigenous languages of Chad are members of the Sara-Bongo-Bagirmi language branch of the proposed Nilo-Saharan language family. In addition to Ngambay, these include Kaba, Deme, Lutos, and Barma/Bagirmi. These languages are mostly used in southern Chad and some of them extend into neighboring countries, especially Cameroon or the Central African Republic.[6]

In parts of Southern Chad, the linguistic landscape is highly diverse. It is a border region between three language families: Niger-Congo, Nilo-Saharan, and Afro-Asiatic, plus a language isolate, Laal. A 2025 study in two villages along the Chari River found that every villager spoke at least three languages fluently, and most spoke at least four. As a result, even though many of the languages have a small number of speakers, they are relatively vibrant, continuing to get passed down through the generations.[7]: 450, 456–457, 471–473 

The Chadian government produced the Chadian National Alphabet [fr], which provides Arabic script and Latin script transcription for various Chadian languages.[8]: 273 

Chadian Sign Language is a poorly-studied language that is considered to be a variant of Nigerian Sign Language, which is itself based on American Sign Language.[9] Andrew Foster, a Deaf African-American educator, introduced ASL instruction to West Africa beginning in the 1960s, eventually establishing 32 schools across 13 countries. Foster began teaching a summer course in ASL for French-speaking teachers, and this in turn led to the founding of a school in Chad in 1976. Although Foster's course taught ASL-based signs, the language may be more of a creole, combining ASL signs with French structure.[10]

Languages used in Chad

from Grokipedia

The languages of Chad comprise French and as the two official languages, established by the national , alongside approximately 129 living languages, the majority of which are indigenous and belong to the Afro-Asiatic, Nilo-Saharan, and Niger-Congo phyla.
This linguistic diversity reflects Chad's ethnic mosaic of over 200 groups and its position as a cultural crossroads in , where —a vernacular form of —functions as a primary , particularly in northern and urban areas.
In the south, languages of the Sara cluster predominate among sedentary populations, while nomadic groups in the north and east favor Afro-Asiatic tongues like those of the Chadic branch; overall remains low at around 22%, with French and dominating formal education and administration despite limited proficiency among the populace.

Overview

Linguistic Diversity and Classification

Chad is home to 123 living indigenous languages, belonging primarily to the Niger-Congo, Nilo-Saharan, and Afro-Asiatic phyla, alongside the official languages French and . These indigenous languages are phylogenetically classified within these major African language families, with Afro-Asiatic encompassing 55 languages (predominantly the Chadic branch), Nilo-Saharan 46, and Niger-Congo 23, plus one . The country's population of approximately 18.5 million speakers reflects this diversity, with indigenous languages serving as first languages for the vast majority. Geographically, Niger-Congo languages predominate in southern Chad, Nilo-Saharan in the east and central regions, and Afro-Asiatic (Chadic) languages in the west and north, reflecting historical migrations and ecological zones from savanna to Sahel. This distribution aligns with the phylogenetic groupings, where southern Bantu-influenced Niger-Congo varieties cluster apart from the northern Chadic tongues linked to broader Afro-Asiatic Semitic and Berber relatives. Chadian Arabic, a vernacular dialect, functions as a de facto lingua franca, spoken by 40-60% of the population as a first or second language, facilitating commerce and interethnic communication across these divides. French, while official, is primarily used in urban and administrative contexts by a smaller , with speaker numbers estimated below 10% nationwide.

Official Languages and Lingua Francas

Chad's official languages are French and , as stipulated in Article 9 of the 1996 (revised through 2005), which mandates their use in government administration, judicial proceedings, and higher education. French, inherited from the colonial administration spanning 1900 to 1960, has remained the primary language for formal and international diplomacy due to its established and in managing a multilingual state. attained co-official status in 1978, reflecting efforts to integrate the predominantly Muslim northern regions into national institutions. Chadian Arabic, a vernacular dialect of Northeastern Arabic (also known as Shuwa Arabic), functions as the principal , facilitating interethnic communication and across the country's diverse . It bridges the Arabic-influenced Islamic north and the animist- and Christian-dominated south, where indigenous languages predominate, thereby promoting practical cohesion in a lacking a dominant indigenous tongue. This dialect's widespread adoption underscores its causal utility in reducing fragmentation amid over 120 indigenous languages and dialects. Promotion of Arabic intensified in the 1970s under President (1975–1979), who sought to balance southern dominance by elevating northern Muslim interests, culminating in 's official recognition amid pan-Arab influences in the . French, however, persisted as the administrative mainstay for its neutrality and precision in legal and technical domains, avoiding over-reliance on 's regional associations. No has emerged as a national , given the profound diversity and absence of a numerically overwhelming ethnic group, compelling reliance on these exogenous vehicles for unity.

Historical Context

Pre-Colonial Linguistic Patterns

The Chadic branch of the Afro-Asiatic language family represents one of the earliest linguistic layers in the Basin, associated with ist economies tied to Sahelian environments. Comparative linguistic reconstructions and indicate that proto-Chadic speakers likely migrated westward from , arriving in the Chad region during the mid-Holocene, with genetic signatures of L3f supporting connections to ancient dispersals around 5,000–3,000 years ago. Archaeological correlates include early sites in the southern basin, where Chadic-speaking groups adapted to phases of Mega-Chad, establishing polities through agro-ism before the . Nilo-Saharan languages form a subsequent stratum, with expansions linked to Nilotic and Central Sudanic branches exploiting lacustrine and fluvial resources. Linguistic and ethnographic parallels suggest Central Sudanic speakers, including proto-Kanembu, settled around by the late , predating the 9th-century Kanem , as evidenced by shared morphological traits like serial verb constructions across Saharan and Sudanic subgroups. In the basin, Sara-speaking groups of Central Sudanic affiliation occupied fertile alluvial zones, supporting sedentary cultivation inferred from comparative grammar and oral traditions of dispersed clans, with no evidence of large-scale displacement until later imperial formations. Minor Niger-Congo elements appear in the southwestern savannas via Ubangian branches, marked by systems and tonal morphologies distinct from dominant families, likely resulting from incremental expansions from the fringes during wetter phases circa 2,000–1,000 BCE, though archaeological traces remain sparse compared to Chadic and Nilo-Saharan distributions. These patterns reflect ecological niches—pastoral Chadic in semi-arid interiors, fishing-farming Nilo-Saharan along waterways—yielding a mosaic of genetic affiliations without implying unidirectional migrations, as substrate influences in Chadic hint at prior Nilo-Saharan substrates.

Colonial Era Influences

French colonial administration in Chad, established as the Military Territory of Chad in 1900 and incorporated into by 1910, designated French as the exclusive language of , command, and nascent formal systems introduced around 1903. Christian missions, primarily Catholic, facilitated initial exposure to French from the early 1900s, focusing on conversion and basic schooling in urban outposts, yet these efforts reached only a fraction of the due to sparse across 's expansive territory. By in 1960, French proficiency was confined to a small assimilated —estimated at under 1% of the roughly 3 million inhabitants—while indigenous languages continued as the primary medium of daily interaction, trade, and rural , underscoring the policy's limited grassroots penetration rather than comprehensive linguistic displacement. Colonial language policies emphasized assimilation through French-medium instruction, stigmatizing local vernaculars in official domains like schools where they were often prohibited, yet no blanket suppression extended to non-administrative spheres; indigenous tongues persisted in , markets, and oral traditions without systematic eradication campaigns. In the Muslim-majority north, French authorities adopted after initial conquests, empowering sultans and qadis who maintained for Islamic jurisprudence, in Quranic schools, and manuscript production, thereby safeguarding these traditions against direct interference. Proselytizing by Christian missions was curtailed in these areas to avert unrest, allowing 's role as a liturgical and scholarly to endure alongside local Chadic and Nilo-Saharan varieties. During the , French colonial personnel, including administrators and ethnographers, initiated rudimentary documentation of through vocabularies and descriptive sketches, as evidenced in archival compilations from the onward, which provided foundational data for subsequent Afro-Asiatic subclassifications despite the era's focus on administrative utility over scholarly depth. These efforts, though sporadic and oriented toward practical needs like census-taking and pacification, contrasted with narratives of utter neglect by highlighting early European engagement with phonetic inventories and dialect mappings in regions like Guéra and Kanem, prefiguring postwar linguistic surveys. Overall, the colonial framework prioritized French in spheres without substantially eroding the phonological or syntactic substrates of over 100 indigenous languages, as substrate influences remained evident in persistent multilingual ecologies.

Post-Independence Language Dynamics

Following independence on August 11, 1960, French retained primacy in administration, , and elite discourse under President François Tombalbaye's southern-dominated regime, with limited accommodation for northern Arabic-speaking groups amid entrenched colonial linguistic hierarchies. This southern bias, rooted in the Sara ethnic majority's control of government institutions, marginalized northern and eastern languages, contributing to early rebellions from onward as northern populations resisted taxation and cultural imposition without corresponding linguistic representation. , already a widespread vehicular tongue among over 850,000 Sahelian and used by approximately 60% of the population as a trade and interethnic medium, gained informal traction in response but lacked official status. The Chadian Civil War (1965–1979) intensified language shifts through mass displacements, as drought, famine, and factional fighting—particularly in the north and east—drove migrations of Arab and pastoralist groups, accelerating the spread of Chadian Arabic as a survival lingua franca in refugee camps, military units, and cross-border exchanges. By 1978, under transitional President Félix Malloum, Arabic was elevated to official status alongside French, reflecting northern political gains and pragmatic recognition of its role in unifying diverse Muslim communities against southern-led central authority. This dual-official framework persisted through Hissène Habré's rule (1982–1990), where Arabization measures expanded Chadian Arabic's institutional footprint in military training, secondary schools, and northern administration to bolster alliances with Arab factions amid Libya-backed incursions and internal purges. Under (1990–2021), policies sustained French-Arabic dominance while experimenting with limited multilingual approaches, yet civil strife's legacy— including persistent displacements—reinforced Arabic's utility in security forces and informal economies. From the 2000s, pilot initiatives in incorporated select indigenous languages for early instruction in rural areas, aiming to improve literacy retention, but analyses highlight enduring hegemony of French and , with minority tongues confined to supplementary roles and promotion departments under-resourced. These dynamics, driven by security imperatives and elite preferences rather than systematic equity, underscore how political instability continually reshaped language ecologies toward vehicular dominance over vernacular vitality.

Major Language Families

Niger-Congo Languages

The Niger-Congo languages of Chad primarily belong to the Adamawa-Ubangi branch, with representatives from both the Adamawa and Ubangi subgroups. Examples include Niellim (nie), spoken in southern ; Koke (kou); Noy (noy); Tunia (tug); and Zan Gula (zna). These languages are spoken by relatively small populations, often numbering in the tens of thousands per variety, contrasting with the larger Nilo-Saharan and Afro-Asiatic families dominant elsewhere in the country. Geographically, Niger-Congo languages in Chad are concentrated south of approximately 10°N latitude, particularly in southeastern border areas adjacent to and the , where they correlate with agriculturalist ethnic groups practicing subsistence farming. Linguistic features include tonal systems for lexical and grammatical distinction, alongside verb morphology that may incorporate extensions for aspect and valency, though serial verb constructions—prevalent in western Niger-Congo branches—are less consistently attested here. Noun class systems, a hallmark of many Niger-Congo languages involving prefixal agreement, appear in rudimentary form in some Ubangi varieties but are often absent or diverged in Adamawa languages, reflecting potential areal influences or deep divergence. The classification of these languages within Niger-Congo rests on shared lexical items and morphological parallels proposed in early comparative work, but the branch's peripheral position has prompted scrutiny over genetic coherence, with critics noting insufficient regular sound correspondences or innovations to substantiate unity beyond a typological Sprachbund. Empirical reconstructions prioritize verifiable cognates in basic vocabulary, yet overclassification risks arise from broad comparative methods that may conflate borrowing with inheritance, particularly given historical migrations around Lake Chad involving contact with Nilo-Saharan speakers. Links to distant subgroups like Bantu remain hypothetical, supported mainly by tentative pronoun and verb-root similarities rather than robust phylogeny.

Nilo-Saharan Languages

Nilo-Saharan languages are spoken predominantly in the central and eastern regions of Chad, encompassing branches such as Saharan and Central Sudanic that reflect verifiable genetic links within macro-Sudanic groupings. According to Ethnologue, Chad hosts 46 languages from this family, many associated with pastoralist and agricultural communities adapted to Sahelian and Sudanese environments. These languages show distributions tied to historical migrations, with Saharan varieties concentrated around Lake Chad and the Tibesti Mountains, while Central Sudanic forms prevail in the south-central prefectorates like Chari-Baguirmi and Ouaddaï. Prominent examples include the Saharan branch's Kanuri, a language with approximately 4 million speakers regionally, deriving prestige from the legacy of the Kanem-Bornu Empire that influenced trade and governance across the from the 9th century onward. In Chad, Kanuri and its relative Kanembu are spoken by communities in Lac and Kanem prefectures, numbering in the tens to hundreds of thousands. Teda and Daza (Dazaga), also Saharan, are used by Toubou groups in the northern Tibesti region, with Daza speakers totaling around 700,000 across and . Central Sudanic languages feature in eastern areas, such as Tama varieties in Biltine and northern Ouaddaï, including Tama, Marari, and Sungor. The Bagirmi language, part of the Sara-Bagirmi subgroup, is spoken by about 45,000 people mainly in Chari-Baguirmi, serving as a marker of pre-colonial kingdoms in the region. Linguistic traits common among these languages include head-marking morphology, where are indicated on verbs or heads rather than dependents, and systems, often involving advanced tongue root (ATR) features that condition vowel quality across words. Kanuri exemplifies this with its agglutinative verb structures reflecting Bornu-era administrative use. identifies over 20 endangered Nilo-Saharan varieties in Chad, such as smaller Central Sudanic lects, attributable to nomadic adaptations and pressures from dominant lingua francas like .

Afro-Asiatic Languages

The Chadic branch dominates the Afro-Asiatic languages of Chad, comprising the majority of indigenous Afro-Asiatic tongues spoken primarily in the northern and western regions around Lake Chad and the Guéra Prefecture. This branch includes approximately 50 languages, such as Musgum in the east and Kera in the southwest, reflecting a diversity shaped by historical migrations and substrate influences from pre-Afro-Asiatic populations. Comparative reconstructions of Proto-Chadic reveal retention of Afro-Asiatic triliteral root structures, adapted into verb derivations, though overlaid with innovations like multi-level tone systems (typically two to three tones) that distinguish Chadic sharply from the non-tonal Semitic languages. Total speakers of Chadic languages in Chad number between 2 and 3 million, concentrated among ethnic groups like the Sara and Kotoko, with many varieties remaining underdocumented. Hausa, a West Chadic language, exerted influence on eastern Chadian varieties through 19th-century migrations tied to the Sokoto Caliphate's expansion, which facilitated trade networks and Islamic proselytization reaching into the Borno Sultanate and Kanem regions bordering . This contact introduced Hausa loanwords into local Chadic lexicons, particularly in domains of , , and , as evidenced by shared vocabulary for administrative terms reconstructed across Central and East Chadic subgroups. A significant Semitic overlay stems from , with emerging as a hybrid incorporating Chadic substrate elements like simplified case marking and tonal influences, functioning as a vehicular language across ethnic divides. Approximately 10-12% of Chad's population, or about 1.5-2 million people, speak as a , mainly among Arabized groups in the zone, while persists in Quranic education and religious texts, reinforcing superstrate effects through lexical borrowing (e.g., terms for and ) into Chadic morphologies. These Arabic integrations, visible in comparative etymologies, highlight causal pathways of cultural dominance via and Islamization since the 11th century, though Chadic resists full Semitic convergence.

Other and Unclassified Languages

In Chad, creole languages are scarce and lack widespread attestation, with no evidence of stable French-based creoles despite colonial history. Arabic-influenced pidgins have been posited in urban trade settings, such as potential variants around Bongor possibly linked to historical Turku Arabic, but these remain underdeveloped and not fully creolized. Claims of distinct Arabic creoles, like among the Babalia Arabs, have been empirically refuted through fieldwork, revealing instead dialectal continuity with rather than creole genesis. Unclassified languages and isolates constitute a small but notable category, numbering fewer than ten based on current inventories, often due to limited documentation and lexical mismatches with established families. Laal, spoken by around 750 individuals (as of 2000 data) in three villages along the in Moyen-Chari Prefecture, exemplifies a proposed isolate; its grammar and vocabulary show no clear affiliation with Niger-Congo, Nilo-Saharan, or Afro-Asiatic phyla, despite geographic proximity to Baguirmi languages. Kujarge, an endangered variety with moribund use near the Chad-Sudan border, is cataloged as unclassified, though comparative wordlists suggest tentative East Chadic ties via shared Afro-Asiatic roots, pending further verification. SIL International's updates in the 2020s have reclassified select marginal languages as dormant or extinct, attributing this to assimilation pressures, including shifts toward Baggara Arab communities in eastern , where original substrates erode without revival efforts. This reflects broader classificatory caution, prioritizing empirical over speculative groupings absent robust evidence.

Sociolinguistic Patterns

Multilingualism and Language Use

Chad exhibits one of the highest levels of in , with most inhabitants proficient in at least two languages and many in three or more, reflecting the country's ethnic and regional diversity. Indigenous languages predominate in familial and ethnic contexts, serving to maintain and daily within communities. , a vernacular form, functions as a primary for , Islamic religious practices, and interethnic interactions, spoken by approximately 60% of the as a vehicular language across rural and urban settings. French, the other , is predominantly employed in bureaucratic administration, formal documentation, and urban professional environments, particularly in cities like where it coexists with multiple indigenous tongues and in practices. In rural southern regions, such as those dominated by Sara-speaking groups, trilingual patterns are common, involving a local Niger-Congo language like Ngambay for home life, alongside French acquired through partial schooling and for regional trade or religious purposes; sociolinguistic surveys indicate widespread comprehension of neighboring languages, facilitating these repertoires. Urban centers like amplify this complexity, with residents often navigating five or more languages in daily exchanges, including Chadic, Nilo-Saharan, and Afro-Asiatic varieties, driven by migration and market dynamics. Northern areas show elevated bilingualism rates exceeding 70%, primarily pairing local languages with , which supports economic stability and social cohesion amid nomadic and sedentary interactions. These patterns underscore pragmatic benefits of lingua francas like and French in enabling cross-ethnic trade and national integration, as evidenced by their role in marketplaces and administration, though they contribute to the relative marginalization of smaller indigenous varieties in non-local domains. Sociolinguistic analyses highlight how such enhances adaptive communication in diverse settings but raises concerns among linguists about the potential of minority languages' through preferential use of dominant codes in expanding commercial networks.

Role in Education, Media, and Administration

In Chad's formal system, French and function as the principal languages of instruction, especially post-primary, in accordance with constitutional mandates requiring their compulsory use across schools. Primary-level experimental initiatives incorporating indigenous mother-tongue primers, implemented in select regions since the mid-2000s with support from organizations like and the World Bank, target initial in approximately 10 local languages but have produced mixed proficiency gains amid national adult rates hovering at 27% as of 2022. These programs, while aiming to leverage familiarity for foundational skills, reveal inefficiencies in scaling indigenous inclusion, as evidenced by persistent low outcomes compared to the entrenched utility of official languages for advanced learning and national assessment. State media outlets, such as Radiodiffusion Nationale Tchadienne and Télé-Tchad under the Office National des Médias Audiovisuels, predominantly operate in French and , with supplementary broadcasts in a handful of indigenous languages like Sara reaching limited audiences. Private FM radio stations extend reach through , a , incorporating some local dialect content, though programming remains marginal and geographically constrained, restricting broader access to information in native tongues. Administrative proceedings, including national legislation, rely on French, while Arabic prevails in northern local courts and customary dispute resolution. Indigenous languages hold no formal status in , effectively excluding non-proficient speakers—comprising most of the —from equitable participation in power structures, as positions demand mastery of languages. This allocation perpetuates disparities, with data indicating that only about 11% of Chadians speak French fluently, underscoring the practical barriers to indigenous linguistic integration in state functions.

Policy, Preservation, and Challenges

Language Policies and Governance

The 1996 of Chad designates French and as the official languages, mandating that outline measures for the promotion and development of indigenous national languages. This bilingual framework, retained in subsequent revisions including the 2018 transitional , seeks to accommodate the country's north-south linguistic divide, with French predominant in southern administration and in northern Islamic contexts. In practice, official governance relies almost exclusively on these exoglossic languages for , judicial proceedings, and , sidelining endoglossic languages despite constitutional recognition. Enforcement of promotion remains negligible, as no comprehensive laws have materialized to integrate indigenous tongues into or since 1996. The 1998 Education Orientation Law nominally supports use in early schooling, yet implementation falters due to resource constraints and prioritization of French-Arabic bilingualism for national cohesion. This approach privileges administrative unity and economic ties within Francophone , where French serves as the primary conduit for international aid, trade, and higher education access. Policy debates underscore persistent north-south tensions, with southern stakeholders viewing Arabic's official status as entrenching northern influence, reminiscent of drives amid 1980s-1990s conflicts under regimes like Hissène Habré's. Proposals in the 2020s for federalized structures incorporating local languages at provincial levels, amid efforts post-Idriss Déby Itno's death, have gone unheeded in the 2023 draft , which reaffirms centralized bilingualism without endoglossic mandates. Such policies empirically prioritize exoglossic proficiency for integration into global markets, as French fluency underpins access to formal and World Bank-supported initiatives in a low-literacy context.

Documentation and Revitalization Efforts

SIL International has led much of the empirical documentation of Chadian languages since signing a partnership agreement with the Chadian government in December 1989 to support among local communities. This includes sociolinguistic surveys, phonological studies, and descriptive grammars for minority languages, such as the Kabalay language in Tandjilé prefecture and Central like Muyang and Mbuko. Documentation projects have also produced audio recordings and cultural materials, exemplified by the Barayin language initiative begun in 2009, which compiles texts, songs, and narratives to preserve oral traditions. Bible translation efforts by SIL have generated written corpora in over a dozen Chadian languages since the 1980s, including full New Testaments or portions in Sara dialects like Sara Madjingay, spoken by multiple southern tribes. Recent church-centric approaches have accelerated translation of 50 Bible stories into ten minority languages using local translators, reducing timelines from years to months. , maintained by SIL, assesses vitality for Chad's roughly 130 indigenous languages, categorizing most as shifting or endangered based on intergenerational transmission data, with fewer than 20% deemed stable or institutional as of the latest profiles. Revitalization initiatives have focused on orthography standardization and , with receiving community-developed writing systems as early as 1969 to enable local and . Partnerships like those in Guéra region have yielded dictionaries in five local languages by 2025, fostering community ownership through workshops. Post-2010 digital efforts remain nascent, with limited corpora or apps tailored to Chadian languages, though general tools for low-resource African tongues suggest potential for expansion via mobile platforms. Measurable outcomes show constrained success, as donor-supported projects—often prioritizing scriptural materials over vernacular media—have not reversed vitality declines in moribund varieties, per indices indicating persistent low speaker retention.

Endangerment and Shift Factors

In Chad, numerous indigenous languages exhibit low vitality according to the UNESCO Language Vitality and Endangerment framework, which assesses intergenerational transmission, absolute speaker numbers, and institutional support, with many small speech communities showing disrupted transmission to younger generations. Languages such as Laal, an isolate spoken by around 800 people in the Middle Chari region of southern , are classified as endangered due to limited domains of use and outward youth migration from isolated villages. Similarly, Ubi and Zerenkel, both Afro-Asiatic languages with fewer than 1,000 speakers each, face decline as primary transmission falters amid broader multilingual repertoires. Primary drivers of this shift include urbanization and rural-to-urban migration, which expose speakers to dominant languages like French and Sara, reducing the prestige and daily utility of isolates and minority tongues in southern and central areas. Exogamous marriages, prevalent in small ethnic groups of the Middle Chari, further erode endogamous transmission by integrating spouses into Sara-dominant households, fostering hybrid that prioritizes vehicular languages over heritage ones. Formal education conducted predominantly in French or reinforces this pattern, as children acquire in national languages at the expense of oral proficiency in local varieties, a dynamic observed across low-vitality communities. In northern Chad, around the Lake Chad basin, insecurity from Boko Haram insurgency since 2009 has displaced over 300,000 people, intensifying economic pressures and potentially accelerating shifts toward as a refuge language in refugee and host communities. This displacement disrupts traditional transmission networks, compounding globalization's homogenizing effects. records four indigenous languages as extinct in Chad, reflecting cumulative losses from these pressures since mid-century, though adaptive multilingualism—where speakers retain minority forms within expanded repertoires—may mitigate total attrition in resilient contexts.
