Forms

δῐᾰλῡ́ω (dialū́ō) [1]

Etymology

It is formed from Ancient Greek δια- (dia-, “apart, asunder”) + λύω (lúō, “to loosen”).[1][2] The verb λύω (lúō) goes back to the Indo-European root Proto-Indo-European *lh₁u- (“to cut off, release”), and corresponds to Latin luō (“to pay, atone”), to which belongs solvō (“to loosen”).[3]

Earliest recorded meaning

Herodotus uses it of Scythian diviners twining and untwining strips of bark (4.67), of night parting those who fight (8.11), and of breaking up an assembly (7.10).[4][5][6]

Semantic evolution

Babiniotis notes that from antiquity the verb combined two kinds of sense, “to break up into parts” and “to destroy, abolish”.[2] From “loose apart” came the breaking up of groups (dismissing a meeting, disbanding an army or a fleet),[4][5] and the dissolving of things into their elements, and Plato defines death as the separation (διάλυσις) of soul and body.[4][5][2] From the parting of enemies came “to reconcile” (Thucydides, Demosthenes) and “to put an end to” enmity or slander, from untying a knotty question “to solve” a difficulty (Plato, Aristotle), and the settling of an account gave “to pay off” a debt (Herodotus, Demosthenes).[4] In the Hippocratic writers it means to relax the body, and in Ptolemaic papyri the passive is used of people wasting away with hunger.[4] In the passive it could also mean “to die” (Xenophon).[4]

In the New Testament the passive is used of a crowd of followers that is dispersed.[7] Medieval vernacular Greek kept the verb, with the popular form διαλύνω (dialýno), still found in dialects.[8] The Modern Greek διαλύω (dialýo) is learned; its sense “to dissolve” (a substance in a liquid) follows French dissoudre.[9][10]
