Pronunciation

  • /soˈluble/, [soˈlu.β̞le][1]

Forms

soluble m or f (masculine and feminine plural solubles)[1]

Etymology

It is borrowed from Latin solūbilis (“that can be loosed or dissolved”).[2][3][1][4] Corominas glosses the Latin word as properly “that can be untied”, and treats it under absolver, with the other learned words of the Latin verb, such as disolver, resolver and solución.[3]

The Latin adjective is post-classical and belongs to solvō (“to loosen, release”).[5] De Vaan explains the verb as a compound of sē- (“away”) and a verb meaning “to loosen”, luō.[6] Related forms are French soluble and Italian solubile.[7]

Earliest recorded meaning

The CDH's first record is in the poems of Miguel de Barrios (c. 1670–1700), which speak of the concepción soluble of the vast chaos, its dissoluble state.[8] Corominas's first record is the Diccionario de Autoridades of 1739, which defines the word as what can be untied or dissolved and quotes a medical text on digestion dissolving the most soluble part of food.[3][9]

Semantic evolution

The negative insoluble is older in Spanish: Corominas dates it 1438.[3] Terreros (1786–1793) gives three uses: in geometry of a problem that can be solved, in pharmacy of what can be melted or dissolved, and of a thing that can fall apart.[7] The chemical sense is frequent from the 1790s, in Luis Proust's work on metallic vitriols and in Cavanilles.[8] In 1818 Francisco Martínez Marina complains that his censors called him soluble among other insults, in the sense “inconstant”.[8]

The Academy's dictionaries of 1817 and 1843 define it as what can be untied or dissolved.[10][11] The 1884 edition gave the Latin etymon and added the figurative sense “that can be resolved”, of a problem.[12] The DLE keeps both senses, “that can be dissolved” and “that can be resolved”.[2]
