You can think about it as the energy that would remain given there is no thermal energy/motion/entropy. So if you imagine molecules in a perfect crystal state, some of them still have residual entropy due to their geometry/orientation possibilities.

I believe residual entropy is the entropy remaining at 0 Kelvin, which means it arises within the arrangement of the atoms themselves. It's calculated using the equation S = kB*ln(w^#molecules), where kB is a constant and w is the number of possible orientations in the molecule.
