Catharsis
Etymology
From Greek “katharsis” (a cleansing or purging), from “kathairein,” to cleanse, ultimately from “katharos,” pure. Aristotle used it in the Poetics for the purgation of pity and fear a tragedy produces in its audience; the word also carried a medical sense of physically purging the body. The modern emotional meaning fuses both.
noun · /kuh-THAR-sis/
The release and relief of strong or repressed emotions, often through art or expression.
What it names
The cleansed, lightened feeling after grief, fear, or anger has been fully felt and let out rather than held in.
Example
Writing the letter she would never send turned out to be a genuine catharsis, draining years of resentment onto the page.
Related idea
A momentary relief eases pressure temporarily; catharsis implies a fuller purging, an emotional reset that leaves you emptied and clearer afterward.
noun · /kuh-THAR-sis/
In medicine, the purging or cleansing of the body, especially the emptying of the bowels.
What it names
Physical evacuation brought on by a purgative, and by extension any thorough cleansing-out of the body.
Example
The physician prescribed a mild cathartic to relieve him.
Related idea
This literal purging is the root of the emotional sense: Aristotle borrowed the medical image to describe how tragedy purges pity and fear. A cathartic, in this sense, is a laxative.
