Etymology

Origin of rarefied

First recorded in 1660–70; rarefy + -ed 2

Explanation

Use the adjective rarefied to describe things that are so stylish, smart, or moral that they seem elevated above the ordinary, like the rarefied conversation of brilliant scholars. To correctly pronounce rarefied, accent the first syllable: "RARE-uh-fied." In addition to high-minded conversation, the word rarefied can also describe the air in high elevations that has less oxygen, like the rarefied air that can be challenging to mountain climbers. Sometimes the quality of airlessness shades the other meaning of the word, implying that the rarefied world of elegant people isn't comfortable to everyone.
