  In a recent paper (Krishan 2021), a two-fluid description of a partially
ionized plasma was presented in which electron fluid and the neutral fluid were
combined appropriately into one fluid, christened as ENe fluid, and treat the
ions as the second fluid. Some of the electrostatic modes of this two-fluid
system were studied. Here, I discuss another possibility in which the ion fluid
and the neutral fluid are combined into one fluid, christened as INe fluid, and
treat the electrons as the second fluid. There can be a huge variation between
the relative masses of the neutrals and the ions. Thus both have to be treated
as the inertia carrying species. After establishing the framework for the
INe-electron fluids, some of the characteristic wave modes of this novel plasma
are investigated.
