Etymology

It is from Ancient Greek διαλύω (dialū́ō, “to loose apart, dissolve”) with the suffix -σις (-sis).[1][2] The verb is λύω (lū́ō, “to loosen”) with διά (diá, “apart”).[3]

Earliest recorded meaning

It is first found in the 5th century BC: Herodotus (3.104) has the “breaking up” of the market, the time when it closed, Thucydides (1.51) the breaking off of a battle, and Euripides (Phoenician Women 435) an end to troubles.[4][2][5]

Semantic evolution

From “loosing apart” the word took many senses: the separation of soul and body at death and the dissolution of the body in Plato; the breaking up of bridges, meetings and armies; the ending of wars, alliances, friendships, partnerships and marriages.[4][2] In Attic law it was the settlement of a dispute by agreement, which the Greek states tried before a formal verdict, and the paying off of debts.[2][6][4] Philosophers set it against composition (σύνθεσις) and coming into being as decomposition, and Dionysius of Halicarnassus used it of the resolution of words into letters.[4][7] In the First Epistle of Clement it is the decay of a seed.[3]

Medieval vernacular Greek also used it for an interpretation, as of a dream, and for a legal compromise.[8] Modern Greek διάλυση (diálysi) is a learned continuation, its senses “dissolution” and “solution” in chemistry shaped by French dissolution and solution.[9]
