sublevel
Floor beneath ground
A sublevel is a division within a level—a secondary tier beneath the main one.
The term appears in video games, where a sublevel is a distinct area accessed from a primary stage, and in architecture or mining, where it designates a floor or stratum below another: The parking garage has three sublevels.
In chemistry, sublevels are divisions of electron shells.
