The mol-ecule of the title compound, C15H15NO2, adopts a trans conformation with respect to the methyl-idene C=N bond and is twisted with a dihedral angle of 26.31 (5)° between the two substituted benzene rings. The eth-oxy group is almost coplanar with the bound benzene ring with a C-O-C-C torsion angle of -179.08 (9)°. In the crystal, mol-ecules are linked by O-H⋯N hydrogen bonds and weak C-H⋯O inter-actions into chains propagating in the [011] and [01-1] directions. C-H⋯π inter-actions are also present.
