  Identifying the inflaton with a pseudo-Goldstone boson explains the flatness
of its potential. Successful Goldstone Inflation should also be robust against
UV corrections, such as from quantum gravity: in the language of the effective
field theory this implies that all scales are sub-Planckian. In this paper we
present scenarios which realise both requirements by examining the structure of
Goldstone potentials arising from Coleman-Weinberg contributions. We focus on
single-field models, for which we notice that both bosonic and fermionic
contributions are required and that spinorial fermion representations can
generate the right potential shape. We then evaluate the constraints on
non-Gaussianity from higher-derivative interactions, finding that axiomatic
constraints on Goldstone boson scattering prevail over the current CMB
measurements. The fit to CMB data can be connected to the UV completions for
Goldstone Inflation, finding relations in the spectrum of new resonances.
Finally, we show how hybrid inflation can be realised in the same context,
where both the inflaton and the waterfall fields share a common origin as
Goldstones.
