Fun Fact

Originally used in physics to describe air thinned at high altitudes, rarefied later took on a metaphorical sense—ideas, lifestyles, or circles of influence that exist far above everyday experience. A rarefied discussion might deal with abstract philosophy, while a rarefied atmosphere could describe both mountaintops and elite social circles. The word captures the tension between refinement and isolation—how elevation, whether intellectual or physical, can be both exhilarating and lonely.
