  A model for neutrino masses and mixing is devised appointing the see-saw
mechanism. The proffered model is fabricated with a combination of Type -I and
Type-II see-saw contributions of which the latter dominates. The scalars and
the leptons in the model are assigned $A4$ charges conducive to obtain the mass
matrices viable for the scheme. The Type -II see-saw mass matrix accommodates
atmospheric mass splitting and maximal mixing in the atmospheric sector
($\theta_{23}=\pi/4$). It is characterized by vanishing solar mass splitting
and $\theta_{13}$ whereas the third neutrino mixing angle is free to acquire
any 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) are
accounted for. Another choice of $\theta_{12}^0=0^\circ$ (no solar mixing) is
reckoned. The subdominant Type-I see-saw constituent of the model propels all
the neutrino oscillation parameters into the ranges allowed by the data which
in its turn get interrelated owing to their common origin. This makes the model
testable 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 Majorana
neutrino mass matrix, $M_{\nu R}$. Only normal ordering is allowed if these
phases 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 inverted
ordering of neutrino masses is also permitted. T2K and NOVA preliminary data
favouring normal ordering and $\delta \sim -\pi/2$ predicts lightest neutrino
mass to be 0.05 eV or more within the framework of this model.
