We introduce a new mechanism for collective polarization dynamics in a polar liquid. This continuum model couples hydrodynamic motions of the liquid to dielectric relaxation by both rotational and translational diffusion of polar molecules. As an application of our theory we calculate the dielectric friction on an ion in a solvent that relaxes only by the translational diffusion mechanism. The result is quite different from dielectric friction dominated by rotational (Debye) relaxation.
