We consider a nonlinear Dirichlet problem driven by the (p,q)-Laplacian and with a reaction having the combined effects of a singular term and of a parametric (p-1)-superlinear perturbation. We prove a bifurcation-type result describing the changes in the set of positive solutions as the parameter λ>0 varies. Moreover, we prove the existence of a minimal positive solution u^*λ and study the monotonicity and continuity properties of the map λ→ u^*λ.
