D. Borah and B. Karmakar have proposed an A_4 flavoured linear seesaw model to realise light Dirac neutrinos. In this comment article, we show that some neutrino Yukawa interactions were missed in the model Ref., thus implying that a different formula would be needed to determine the effective neutrino mass matrix, with significantly different results. Our result shows that, unlike stated in Ref., that the inverted neutrino mass spectrum is not ruled out.
