This paper presents a bi-clausal analysis for Kirundi (Great Lakes Bantu; J/D62) cleft constructions. In doing so, it critically examines one diagnostic asymmetry previously presented for differentiating between bi-clausal and mono-clausal cleft constructions in other Bantu languages. Kirundi is shown to have two cleft constructions. This paper proposes that the two structures are derived by A-bar movement of the clefted constituent into the left-edge of the cleft clause, followed by embedding of the cleft clause by either a verbal or a non-verbal copula. The implications of this latter proposal concerning non-verbal embedding material is briefly considered.
