In this paper, we aim at analyzing the Basque inflectional morpheme - (k)i called dative flag after Trask (1997). We will propose this morpheme - (k)i to be an applicative head, as suggested in Elordieta (2001) or Rezac (2006) among others. Moreover, we will propose this applicative to be an incorporated preposition in the spirit of Trask (1981: 289). The idea of - (k)i being an applicative/incorporated preposition can be combined with both the derivational account for applicatives (Baker 1988) and the base - generation analysis (McGinnis 1988), developed also for Basque. Nonetheless, the applicative/incorporated preposition analysis of - (k)i departs considerably from the typological definition of Bantu applicatives. Actually, the presence of - (k)i is mo re pervasive in Basque than applicatives in Bantu languages, as it is attested in both differential object marking (Odria 2014) (vs. Bantu languages, Bresnan & Mchombo 1988) and allocutives (Oyharçabal 1993; Haddican 2015). Although this paper will not gi ve an alternative analysis to those already developed in Basque, it aims at raising some questions on the nature of - (k)i that might have consequences in the general discussion on applicatives.
