We describe a two-field model that generalizes Natural Inflation, in whichthe inflaton is the pseudo-Goldstone boson of an approximate symmetry that isspontaneously broken, and the radial mode is dynamical. We analyze how thedynamics fundamentally depends on the mass of the radial mode andcalculate/estimate the non-Gaussianities arising from such a scenario.
