We discuss the issue of how precisely we can measure the primordial power spectrum by using future observations of 21 cm fluctuations and cosmic microwave background (CMB). For this purpose, we investigate projected constraints on the quantities characterizing primordial power spectrum: the spectral index n_s, its running alpha_s and even its higher order running beta_s. We show that future 21 cm observations in combinations with CMB would accurately measure above mentioned observables of primordial power spectrum. We also discuss its implications to some explicit inflationary models.

Large Field Polynomial Inflation in Palatini $f(R,\phi)$ Gravity
Large-field polynomial inflation in Palatini f(R, phi) gravity can match Planck and BICEP/Keck data over broad parameter regions, and a negative R-squared coupling can suppress the tensor-to-scalar ratio to CMB-S4 levels.

Quadratic, Higgs and hilltop potentials in the Palatini gravity
In Palatini gravity, quadratic inflation matches CMB data only for small nonminimal coupling and efficient reheating, while hilltop potentials match only below the vacuum expectation value with tiny coupling.
