A Nvon-Nvon Sociocultural Dataset is a sociocultural and onomastic dataset documenting the Nvon-Nvon community of Cameroon (the Mvoń-Mvoń (also “pu Buanda”) of the Yokadouma area), collected under the project "Projet de confection d'un didacticiel sur la composition des peuplements au Cameroun" (a didactic-software project on the composition of Cameroon's settled peoples), coordinated by Prof. Emmanuel Ngue Um for CERDOTOLA (the Inter-State Institution of scientific co-operation for the preservation, diffusion and valorization of the African cultural heritage) during the project's pilot data-collection phase in March-April 2020. Unlike a purely linguistic corpus, the dataset foregrounds the community itself as the unit of documentation: its history, social organisation, religious life and material culture, with onomastics, common expressions and a numeral system providing a linguistic component elicited in the community's own speech (recorded in the International Phonetic Alphabet, or in a Latin-based approximation where IPA was not available to the fieldworker). Self-designated Mvoń-Mvoń (also known as “pu Buanda”), the group overlaps with the Mbimo, Bayègè, Ngbaya and Kakɔ'o, and, being dispersed across several Cameroonian towns, its speech is heard beyond its home area. The group has always lived at Yokadouma, which it regards as its original, ancestral land. Social organisation is built around kinship and family landholding; the chief decides matters of communal life after consulting notables, patriarchs and matriarchs by consensus, and descent is patrilineal. Marriage proceeds from a visit and reception by the bride's family to a formal hand-request and bridewealth of goats, cooking pots, machetes and blankets. An ancestral cult, formerly led by an elder in the evening (“the great *matim*”), is no longer widely practised. Incest is strictly forbidden and traditionally resolved by separating the parties involved. Men farm, hunt, trade and raise small livestock; women farm, fish, trade and gather; dishes such as *kouem*, *kɔkɔ* and *ngouzok*, and wild mango (*ndip*), are staples, alongside a fermented-banana drink (*Arvi*). Traditional bark-cloth garments (*Yete*, *Ekuán*) are worn by both men and women at major ceremonies, and the group notes close cultural and linguistic affinity with the Mbimo and Bakando. The dataset's primary added value lies in documenting the Nvon-Nvon community's own self-description — its social organisation, kinship and marriage practices, religious and symbolic life, economy and material culture, and internal system of personal, ethnic and place names — rather than only its named language or dialect. This community-centred, ethnographic design distinguishes it from language-only documentation, while the accompanying onomastic, common-expression and numeral-system data still make the dataset usable for lexicographic and comparative linguistic work on the Nvon-Nvon variety.

You agree not to use the data for: profiling, surveillance or any purpose prejudicial to the interests of the individuals or community described; caricaturing, stereotyping, or otherwise misrepresenting the community documented; Generative AI; reproduction; duplication; modification; augmentation; copying; distribution; transmission; display; sale; transfer; publication or creation of derivative works without the explicit permission of the legal owner of the dataset.
Intended Use
(a) Ethnographic and cultural documentation: - Sociocultural and anthropological research: The narrative responses (identity, residence and mobility, social and political organisation, kinship and marriage, religious and symbolic life, economy and material culture) support ethnographic, anthropological and sociolinguistic research on the Nvon-Nvon community, and complement rather than replace existing ethnographic and anthropological scholarship. (b) Onomastic and toponymic research: - Personal-name, ethnonym and toponym documentation: The structured onomastic entries, each tagged with a semantic primitive and grammatical category, support onomastic and lexicographic research and comparative naming-practice studies across Cameroonian communities. (c) Linguistic and lexicographic tasks: - Lexicon documentation and comparative numeral typology: The common-expression and numeral-system tables, transcribed where possible in IPA, are useful for building basic lexical resources for the Nvon-Nvon variety and for comparative numeral-system typology across Cameroonian languages. (d) Pedagogical and educational-software use: - Didactic-software content: As part of the pilot phase of a project building educational (“didacticiel”) material on the composition of Cameroon's settled peoples, the dataset supports the development of teaching content on the Nvon-Nvon community's history, culture and onomastics. (e) Cultural modeling and intercultural dialogue: - Cultural modeling: The sociocultural, onomastic and linguistic data in this dataset can be used to build and enrich interactive network-based representations of cultural communities, modeling the relationships and affinities between Cameroonian communities across historical, linguistic, geographic, social and cognitive dimensions. An example of such cultural modeling in the African multicultural and multilingual context is the CamRhizome interactive visualization, accessible at https://ngue-um.github.io/Enseignement-Apprentissage-LN/#/reseau, which maps intercommunal connections among 20 Cameroonian language communities and can serve as a tool for enhancing intercultural dialogue in African multicultural and multilingual spaces.

Note: The fieldwork interview audio recording is not yet included in this release. It will be added in a subsequent update. Recordings were collected on the fieldwork sites and document the interaction between the interviewer and the interviewee.
Self-designated Mvoń-Mvoń (also known as “pu Buanda”), the group overlaps with the Mbimo, Bayègè, Ngbaya and Kakɔ'o, and, being dispersed across several Cameroonian towns, its speech is heard beyond its home area. The group has always lived at Yokadouma, which it regards as its original, ancestral land.
Social organisation is built around kinship and family landholding; the chief decides matters of communal life after consulting notables, patriarchs and matriarchs by consensus, and descent is patrilineal. Marriage proceeds from a visit and reception by the bride's family to a formal hand-request and bridewealth of goats, cooking pots, machetes and blankets.
An ancestral cult, formerly led by an elder in the evening (“the great matim”), is no longer widely practised. Incest is strictly forbidden and traditionally resolved by separating the parties involved.
Men farm, hunt, trade and raise small livestock; women farm, fish, trade and gather; dishes such as kouem, kɔkɔ and ngouzok, and wild mango (ndip), are staples, alongside a fermented-banana drink (Arvi). Traditional bark-cloth garments (Yete, Ekuán) are worn by both men and women at major ceremonies, and the group notes close cultural and linguistic affinity with the Mbimo and Bakando.
The interview was conducted with the local expert speaking Nvon-Nvon. Rubrique 4 of the questionnaire elicited 157 common bilingual expressions (salutations, politeness formulas and everyday phrases), of which 150 have an endogenous-language form recorded to date; rubrique 5 elicited a 107-item numeral system, of which 107 have an endogenous-language form recorded to date. Together with the anthroponyms, ethnonyms and toponyms in rubrique 3, these fields constitute the dataset's linguistic component and are transcribed, where possible, in the International Phonetic Alphabet (IPA/API), per the questionnaire's instructions; where a fieldworker was not proficient in IPA, a Latin-alphabet approximation was used instead. No audio recordings are included in this release, although the questionnaire's protocol called for the full interview to be captured on dictaphone.
The dataset was collected through a questionnaire designed to gather sociocultural and onomastic information about the Nvon-Nvon community. This was done during the pilot data-collection phase (March-April 2020) of the "Projet de confection d'un didacticiel sur la composition des peuplements au Cameroun," coordinated by Prof. Emmanuel Ngue Um for CERDOTOLA (Centre International des Civilisations Bantu / Institution Inter-Etats de cooperation scientifique pour la preservation, la diffusion et la mise en valeur du patrimoine africain), in partnership with the Ecole normale superieure de Bertoua. Record identifier: NVNV_2020_001.
The dataset represents a sociocultural and onomastic questionnaire designed to elicit the identity, history, social organisation, religious life, economy and material culture of a named community in Cameroon, together with a structured record of its personal names, ethnic names and place names, common bilingual expressions, and numeral system. The questionnaire was developed for the pilot phase of a project building educational (“didacticiel”) material on the composition of Cameroon's settled peoples; unlike a purely linguistic questionnaire, its entry point and primary unit of documentation is the community, not its language or dialect, although a linguistic component (onomastics, common expressions, numeral system) is elicited throughout in the community's own speech.
The dataset comprises 52 narrative question/answer entries (rubriques 2 and 3.1-3.6); 4 anthroponym entries, 5 ethnonym entries and 4 toponym entries (rubrique 3); 150 of 157 common expressions with an endogenous-language form recorded (rubrique 4); 107 of 107 numeral-system entries with an endogenous-language form recorded (rubrique 5); and a fixed 65-item reference table of NSM semantic primitives (annex).
