Pronunciation

  • Classical: [dɪsˈsɔɫ.woː][1]
  • Ecclesiastical: [disˈsɔl.vo][1]

Forms

dissolvō (present infinitive dissolvere, perfect active dissolvī, supine dissolūtum); third conjugation[1]

Etymology

It is formed from Latin dis- (“apart”) + solvō (“to loosen”).[2][1][3] De Vaan explains solvō as a compound of ⟨*se-⟩, “away”, and luō (“to loosen”), which goes back to Proto-Italic *luwe/o- and Proto-Indo-European *lewH- (“to cut loose”), cognate with Ancient Greek λύω (lúō, “to loosen”).[4]

Earliest recorded meaning

De Vaan gives Plautus as its first author.[4] In Terence's Phormio a young man wants a little money quī dissolverem quae dēbeō, “to pay what I owe”.[2]

Semantic evolution

It is to break something into its parts, to take to pieces, as Phidias' shield in Cicero, and to disband a group (Tacitus).[2] It is to melt or dissolve, as Lucretius' sun melting ice, to make darkness vanish, and of medicines to dispel an ailment.[2] It is to set free, release from an obligation, and to undo a knot or bond, and Seneca uses it of solving a problem.[2] It is to pay a debt, to weaken or wear out (Lucretius), and to put an end to agreements or institutions, as Sisenna's broken treaties; of arguments it is to refute, as Cicero says some charges are dispelled with a joke.[2]

Church Latin glosses it “dissolve, loose, destroy, scatter, free, release”.[5] English dissolve (late 14th century) comes from it.[3]
