Mandinka (Mande) has two variants of the genitival construction (or adnominal possessive construction). In the direct genitival construction, the possessor NP immediately precedes the possessee, without any morphological material, as in Jàatàkúndáa kòlóŋò ‘the well of the Jaatakundaa neighborhood’, whereas in the indirect genitival construction, the possessor NP is marked by the postposition lá, as in Jàatàkùndàŋkôolú lá kòlóŋò ‘the well of the Jaata family’. The direct genitival construction is formally distinct from N+N compounds, as in nìnsìsíŋò ‘a/the cow leg’ vs. nìnsóo sìŋôo ‘the leg of a/the cow’. Functionally, this coding split show unusual properties, in comparison with most of the languages in which formally similar coding splits have been observed. Crucially, any noun can fulfill the role of head in the direct construction, depending on the semantic nature of the possessor and of its relation to the possessee. In this presentation, I will discuss the semantic distinctions that may be relevant to the choice between direct and indirect genitives.
