κλεψύδρα

Forms

κλεψῠ́δρᾱ (klepsúdrā) f (genitive κλεψῠ́δρᾱς); first declension^[1]

Etymology

It is a compound from Ancient Greek κλέπτω (kléptō, “to steal”) + ὕδωρ (húdōr, “water”), literally “water thief”.^[1][2] Beekes describes it as a governing compound with the first member κλέψαι (klépsai), the zero grade of the second member as in ἄνυδρος (ánudros, “waterless”), and the feminine ending -α.^[3]

Earliest recorded meaning

Its first sense is a pipette: Empedocles, in the 5th century BC, describes a small vessel with holes in its base and an air-vent at the top, used to lift small quantities of liquid.^[4][5]

Semantic evolution

In Athens the word came to mean the water-clock, a vessel with a narrow hole at the bottom through which water ran out slowly, used to time speeches in the law-courts, and Aristophanes and the Aristotelian Constitution of the Athenians describe it.^[4][5][2] It was also used to measure military watches (Aeneas Tacticus) and in astronomy (Proclus).^[4] Aristotle also uses the word for the pipette in his physics.^[4] It was the name of an intermittent spring on the Acropolis at Athens and of another at Ithome.^[4]

Latin borrowed it as clepsydra.^[6] Modern Greek κλεψύδρα (klepsídra) is a learned word for a time-measuring instrument of two vessels joined by a narrow passage, through which water or sand runs, so also an hourglass.^[7]
