  Observations with modern radio telescopes have revealed that classical novae
are far from the simple, spherically symmetric events they were once assumed to
be. It is now understood that novae provide excellent laboratories to study
several astrophysical properties including binary interactions, stellar
outflows, and shock physics. The ngVLA will provide unprecedented opportunities
to study these events. It will enable us to observe more distant and fainter
novae than we can today. It will allow us to simultaneously resolve both the
thermal and non-thermal components in the ejecta. Finally, monitoring novae
with the ngVLA will reveal the evolution of the ejecta in better detail than is
possible with any current instrument.
