We present results for the isovector axial, (induced) pseudoscalar, electric, and magnetic form factors of the nucleon. The calculation was done using MILC 2+1+1-flavor HISQ ensembles with three lattice spacings 0.12, 0.09, 0.06 fm and three pion masses, approximately, 310, 220, 130 MeV. The same calculation is performed with the 2+1-flavor clover ensembles with, approximately, 300 and 190 MeV pion masses. We report charge radii from the dipole and model independent z-expansion fits.
