Forms

κᾰθᾰρτῐκός (kathartikós) m (feminine κᾰθᾰρτῐκή, neuter κᾰθᾰρτῐκόν); first/second declension[1]

Etymology

It is formed from Ancient Greek καθαίρω (kathaírō, “to cleanse, purify”) + -τικός (-tikós).[1][2][3] The Middle Liddell derives it from the agent noun καθαρτής (kathartḗs, “purifier”).[4][5]

Earliest recorded meaning

Plato uses it of what cleanses or purifies, for instance of soda as the kind of substance that removes oil and dirt, and in the Sophist the art of purification is ἡ καθαρτική.[6][7] In the Hippocratic writings it is a medical word for what promotes a purge.[6][8]

Semantic evolution

Aristotle applied it to melodies that have a purifying effect on the listener, in the sense of κάθαρσις (kátharsis).[6][7] In medicine it came to mean “purgative”: Plutarch speaks of a purgative drug, and Galen and Dioscorides use it often, while the neuter plural meant “purgatives”.[6][2][8] Most of the word's ancient occurrences are in the medical writers of the 2nd century AD.[8] Hierocles speaks of “purifying virtues”.[6]

Medieval Greek used it of what purifies the soul, and the neuter as a noun for a purgative drug.[9] Modern Greek καθαρτικός (kathartikós) is a learned continuation; its neuter καθαρτικό is the usual word for a laxative.[10][11] Through New Latin catharticus it gave English cathartic (1610s, first of medicines).[1][12]
