Several recent works have claimed that the Weak Gravity Conjecture (WGC) excludes super-Planckian displacements of axion fields, and hence large-field axion inflation, in the absence of monodromy. We argue that in theories with N≫1 axions, super-Planckian axion diameters D are readily allowed by the WGC. We clarify the nontrivial relationship between the kinetic matrix K --- unambiguously defined by its form in a Minkowski-reduced basis --- and the diameter of the axion fundamental domain,

... sizing that in general the diameter is not solely determined by the eigenvalues f_1^2 < ... < f_N^2 of K: the orientations of the eigenvectors with respect to the identifications imposed by instantons must be incorporated. In particular, even if one were to impose the condition f_N S M_pl/f_N, with S a fixed constant, but in the universal limit S≳ S√(N)M_pl/f_N. Thus, having f_N>M_pl does not immediately imply the existence of unsuppressed higher harmonic contributions to the potential. Finally, we argue that in effective axion-gravity theories, the zero-form version of the WGC can be satisfied by gravitational instantons that make negligible contributions to the potential.
