Forms
κᾰ́θᾰρσῐς (kátharsis) f (genitive κᾰθᾰ́ρσεως); third declension[1] Elean κόθαρσις.[2]
Etymology
It is formed from Ancient Greek καθαίρω (kathaírō, “to cleanse”) + -σις (-sis).[1][3] The verb comes from καθαρός (katharós, “pure, clean”), which Beekes considers Pre-Greek because of its variation between α and ο.[4][5]
Earliest recorded meaning
Herodotus uses it for the ritual cleansing of a man from bloodguilt.[2][6][7]
Semantic evolution
The word covered every kind of purging, of visible dirt and of invisible defilement.[6] Plato defines purification as separating the soul as far as possible from the body, and uses it in the Cratylus and the Sophist.[2][8] In Hippocratic medicine it was the clearing off of morbid humours, natural or caused by drugs, and also the menses.[2][8] Aristotle's definition of tragedy, which through pity and fear accomplishes the purging of such emotions, gave it its most famous use.[2][8]
Later it meant the cleansing of the universe by fire for the Stoics, the clarification of a problem for Epicurus, the pruning of trees for Theophrastus, and the winnowing of grain in the papyri.[2] The Septuagint uses it for a woman's purification after childbirth.[9] The Latin rites of lūstrātiō were what the Greeks called κάθαρσις.[10]
Medieval Greek used it for moral purification and for bodily evacuation, and it survives as κάθαρση (kátharsi).[11][1] English took catharsis in 1770 as a medical term for purging; the sense of emotional release dates from 1872, and the psychotherapeutic one from 1909.[12]
