Condescension
Etymology
From Latin "condescendere" (to come down to), "con-" (together) + "descendere" (to descend). It once named a genuine virtue — a superior graciously coming down to another’s level — but the "coming down" came to feel like a reminder of the distance, and the word soured.
noun · /kon-di-SEN-shun/
A patronizing manner that treats others as inferiors while appearing gracious.
What it names
The insult wrapped in politeness — help or praise delivered from a height.
Example
The consultant explained email to a room of engineers with a condescension you could taste.
