airless
Lacking any atmosphere
Airless describes spaces without fresh or circulating air: an airless basement, the airless confines of a submarine.
The word suggests stuffiness and discomfort.
By extension, airless characterizes things lacking vitality or atmosphere: an airless performance, airless prose.
In technical contexts, airless refers to environments literally without air, like the vacuum of space.
