A model for neutrino masses and mixing is devised appointing the see-sawmechanism. The proffered model is fabricated with a combination of Type -I andType-II see-saw contributions of which the latter dominates. The scalars andthe leptons in the model are assigned $A4$ charges conducive to obtain the massmatrices viable for the scheme. The Type -II see-saw mass matrix accommodatesatmospheric mass splitting and maximal mixing in the atmospheric sector($\theta_{23}=\pi/4$). It is characterized by vanishing solar mass splittingand $\theta_{13}$ whereas the third neutrino mixing angle is free to acquireany value of $\theta_{12}^0$. Particular alternatives of $\theta_{12}^0$corresponding to the popular lepton mixings viz. $\theta_{12}^0=35.3^\circ$(tribimaximal), $45.0^\circ$ (bimaximal), $31.7^\circ$ (golden ratio) areaccounted for. Another choice of $\theta_{12}^0=0^\circ$ (no solar mixing) isreckoned. The subdominant Type-I see-saw constituent of the model propels allthe neutrino oscillation parameters into the ranges allowed by the data whichin its turn get interrelated owing to their common origin. This makes the modeltestable in the light of future experimental data. As an example, $\theta_{23}$emerges in the first (second) octant for normal (inverted) ordering.CP-violation is governed by phases present in the right-handed Majorananeutrino mass matrix, $M_{\nu R}$. Only normal ordering is allowed if thesephases are absent. If $M_{\nu R}$ is complex the Dirac CP-violating phase$\delta$, is capable of being large, i.e., $\sim \pm \pi/2$, and invertedordering of neutrino masses is also permitted. T2K and NOVA preliminary datafavouring normal ordering and $\delta \sim -\pi/2$ predicts lightest neutrinomass to be 0.05 eV or more within the framework of this model.
