The charm semileptonic decays D+ → ηe+ve and D+ → η'e+ve are studied with a sample of e+e- collision data corresponding to an integrated luminosity of 2.93 fb-1 collected at $$ \sqrt{s}=3.773 $$ GeV with the BESIII detector. We measure the branching fractions for D+ → ηe+ve to be (10.74 ± 0.81 ± 0.51) x 10-4, and for D+ → → η'e+ve to be (1.91 ± 0.51 ± 0.13) x 10-4, where the uncertainties are statistical and systematic, respectively. In addition, we perform a measurement of the form factor in the decay D+ → ηe+ve. All the results are consistent with those obtained by the CLEO-c experiment.
