Strictly singular operators on variable exponent (or Nakano) function spaces L^p(⋅) are characterized in terms of being ℓ_q-strictly singular for the values q in the essential range R_p(⋅) of the exponent function. This extends a result of L. Weiss [On perturbations of Fredholm operators in L_p-spaces, Proc. Amer. Math. Soc. 67 (1977), 287-292] for L^p-spaces.
