Ethnobotanical Surveys and Morphological Analysis of Medicinal Plant Names in Lɔ́mɔngo (Lomongo) C60 at the Elandisha Mavaolo Protected Area in Northeastern DRC.

The aim of this study is to contribute to the documentation of Lomongo, a Bantu language spoken in the Democratic Republic of Congo (DRC). In this study, we focused on two morphological aspects of medicinal plant names in Lomongo: nominal morphology, and morpho-syntax. To collect the data, we engaged with two categories of informants: primary informants (traditional healers); and secondary informants (native Lomongo speakers). Ethnobotanical and ethnolinguistic surveys were conducted in the 'Elandisha' Mavaolo area through participant observation, semistructured interview guides, audio recordings, and photographs. The plants identified were documented in situ with the assistance of botanists from 'Matiti-Lisanga,' an interdisciplinary ethnobiology research platform. Herbarium samples were deposited at the herbarium of the Faculty of Sciences at the University of Kisangani. From these surveys, we identified 23 plant occurrences. In terms of nominal morphology, we found that pairing 3/4 (43.5% of occurrences) was predominant. Our results indicate that the Lomongo class system aligns with Proto-Bantu semantics. For morphosyntactic structures, 10 plant names (43.5%) exhibited simple or morphosemantic structures, followed by simple compositions with 7 occurrences (30.4%). This study highlights the importance of ethnobotanical data in documenting Lomongo. However, a larger set of lexical items and a broader pool of informants would further enhance the role of ethnobotanical data in describing this language. [ABSTRACT FROM AUTHOR]
