Forms

soldar (first-person singular present sueldo, first-person singular preterite soldé, past participle soldado)[1]

Etymology

It continues inherited from Old Spanish soldar, inherited from Latin solidō (“to make solid, consolidate”).[2][1][3] In classical Latin the verb meant “to consolidate, harden”; the sense “to solder” is late, and already in Avitus around the year 500.[4][3] The Latin verb is formed on solidus (“solid, whole”),[5][6] which de Vaan reconstructs as Proto-Indo-European *solh₂-i-dʰh₁-o- (“entire”) and connects with salvus (“safe”) and sollus (“whole”).[7]

The same Latin verb gave Portuguese soldar, Catalan soldar, Aranese suda, French souder (from solder) and Italian saldare (in the 13th century with ⟨o⟩).[8][9] Its learned doublet is solidar; sueldo continues the Latin adjective in its Late Latin use as the name of a gold coin.[1][4]

Earliest recorded meaning

Corominas dates the verb to Alfonso de Palencia (1490) and Nebrija, but the DPCAX has it earlier in Alfonso X's Lapidario (1250–1279): a stone mixed with water makes a strong glue that bookbinders and carpenters use en soldar las taulas “to join the boards”.[4][3][10] An astronomical text of 1277 uses it for caulking: suelda la con cera & con resina assi cuemo sueldan las naues “seal it with wax and resin, as ships are sealed”.[10]

Semantic evolution

Nebrija renders soldar by Latin solido and consolido, soldar travando “to join by interlocking” by committo, and soldar con plomo “to solder with lead” by applumbo.[11][12] Covarrubias defines it as joining something of metal, “as if solidar”.[13] Autoridades has it for joining something naturally or artificially, with a quotation from Laguna's Dioscorides on earthworms that sueldan los nervios cortados “knit severed sinews”, and figuratively for mending a blunder with deeds or words, quoting the Celestina.[14] The Academy's 1843 dictionary adds that it is said properly of metals.[15]

The healing sense is old in the Americas too: in 1548 a writer in Santo Domingo says that whoever is hurt nunca suelda su dolor “never heals his pain”, and in 1549 a remedy suelda a broken leg or arm.[16] Cervantes writes that riches can soldar muchas quiebras “mend many breaches”.[17]

Usage notes

Soldar is conjugated like contar: sueldo, sueldas, suelda.[14][21] Cuervo in Bogotá and Román in Chile criticised the regular forms soldo, soldas.[22][23] Old Spanish also had a rarer verb soldar “to pay (a soldier)”, related to soldada “wages”, in the Libro de Alexandre and the Libro de Apolonio.[4]
