Forms

κᾰτᾰρρέω (katarrhéō) [1]

Etymology

It is formed from Ancient Greek κατα- (kata-, “down”) + ῥέω (rhéō, “to flow”), with the ρ doubled after the prefix, as in διαρρέω (diarrhéō) and ἀπορρέω (aporrhéō).[1][2][3] The simple verb, from older *ῥέϝω (*rhéwō), continues Proto-Indo-European *sréw-e-ti, from the root *srew- (“to flow”), and matches Sanskrit स्रवति (srávati, “flows”).[4]

Earliest recorded meaning

Homer uses it twice in the Iliad, of blood that runs down from a wound.[3][5]

Semantic evolution

Herodotus uses it of phlegm running down from the head, and Xenophon and Demosthenes of rivers and of water.[5] In Aristophanes people stream down in a crowd, and in Thucydides the Athenians, pressed together, fall into the river.[5] Hippocratic writers use it of a patient sliding down the bed, and Xenophon and Theophrastus of fruit and leaves that drop.[5]

From the 4th century BC it also means to collapse: Demosthenes uses it of a power that crumbles of itself, a fragment of Aristotle says that the city's courage collapsed, and later writers use it of a crater falling in and of a roof.[5][6] In Euripides' Trojan Women the temples run with blood.[5] The bucolic poets use it for something that falls to someone's lot.[5]

In the Septuagint it means to drip down, to fall off and to stream down, and once for a soul that wastes away.[7] The Apocalypse of Peter uses it of pus flowing down.[8] Modern Greek uses it as a learned verb meaning to collapse, influenced by French s'écrouler.[9]
