Abstract
D. Borah and B. Karmakar [1] have proposed an A4 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. [1], 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. [1], that the inverted neutrino mass spectrum is not ruled out.
