κύστις

Forms

κῠ́στῐς (kústis) f (genitive κῠ́στεως); third declension^[1]

Etymology

Wackernagel analysed it as a noun with the suffix -τις (-tis) added to the zero grade of a verbal root meaning “to blow, hiss”, Proto-Indo-European *ḱwes-, which is found in a Sanskrit verb meaning “to blow, breathe”.^[2][3][4] Beekes finds the connection possible but not evident, and notes that the by-form κύστιγξ (kústinx), with its suffix -ιγξ (-inx), could instead point to a Pre-Greek word.^[2] Chantraine and Frisk take that by-form as a later formation modelled on φῦσιγξ (phûsinx).^[3][4] Wiktionary also mentions a derivation from Proto-Indo-European *(s)kewH- (“to cover”) or from κύω (kúō, “to be pregnant, swell”).^[1] The comparison of the Sanskrit root with Latin queror (“to complain”) is far from evident, and κύσθος (kústhos) is not related.^[2][3][4]

Ancient grammarians derived it from κεύθω (keúthō, “to hide”), because the bladder hides the urine, or from κυέω (kuéō, “to be pregnant”), because the organ swells with urine.^[5]

Earliest recorded meaning

It is first found in the Iliad, twice, meaning the bladder.^[6][7][8]

Semantic evolution

In classical Greek it is the urinary bladder of a person, in medical writers and in Plato's Timaeus,^[7][9] and also an animal's bladder blown up like a balloon or used as a pouch: Aristophanes compares the wind swelling out the clouds to someone blowing up a bladder.^[7][9] Aristotle uses the plural for the bags under the eyes, and the late veterinary writers for an ulcer on a horse's back.^[7]

Modern Greek has the learned word Modern Greek κύστη (kýsti), the bladder and other sacs of the body; its sense “cyst” was taken from French kyste, itself made from the Greek word.^[10][11] The Italian learned prefix cisto- comes from the same stem.^[12]
