Of the approximately 400 known Galactic classical novae, only ten of them,
the recurrent novae, have been seen to erupt more than once. At least eight of
these recurrents are known to harbor evolved secondary stars, rather than the
main sequence secondaries typical in classical novae. In this paper, we propose
a new nova classification system, based solely on the evolutionary state of the
secondary, and not (like the current schemes) based on the properties of the
outbursts. Using archival optical and near-infrared photometric observations of
a sample of thirty eight quiescent Galactic novae we show that the evolutionary
state of the secondary star in a quiescent system can predicted and several
objects are identified for follow-up observations; CI Aql, V2487 Oph, DI Lac
and EU Sct.
