Pronunciation

  • Brazil: /ˈsow.du/, [ˈsoʊ̯.du][1]
  • Portugal: /ˈsol.du/, [ˈsoɫ.du][1]

Forms

soldo m (plural soldos)[1] Houaiss's historical forms are solidos (933) and soldo (984) in Latin charters, and soldo, solído and solldo in the 15th century.[2]

Etymology

It is inherited from Late Latin soldus (“a gold coin”), the contracted form of Latin solidus (“solid, whole”), written Old Galician-Portuguese soldo in the old language.[2][1][3] The adjective was used as a noun for the coin, with nummus (“coin”) understood: “a whole, solid coin”, and Late Latin already had it as the name of a gold coin.[2][4] The contracted form already appears in Varro and Horace.[5]

The same word is Italian soldo, French sou, Old Occitan sol, Catalan sou, Spanish sueldo and Galician soldo.[6][7] Spanish has soldo from 1062–1063 and the present form from 1129.[8] The learned doublet is sólido.[1]

De Vaan derives the Latin adjective from Proto-Indo-European *solh₂-i-dʰh₁-o- (“entire”), from the root of salvus (“safe, whole”) and sollus (“whole”).[9]

Earliest recorded meaning

Latin charters of Portugal already have solidos in 933 and uno soldo gallecano in 984.[2][3] In the Romance texts a document of 1228 has in cada ano un soldo “one soldo every year”, and one of 1253–1254 XXX soldos de renda, with the sense of a coin of small value.[3]

Semantic evolution

In the medieval language the soldo was a coin of little value: a cantiga d'escarnho of Alfonso X tells of one who would not give ũũ soldo to redeem his soul, and the Cantigas de Santa Maria count cinco soldos e mealla.[3][10] Viterbo writes that Portugal had soldos of gold, silver and copper, and that the copper ones lasted until King João II.[11] Bluteau adds that before 1395 twenty soldos made one old livra of 36 réis.[12]

Houaiss dates the sense “pay for a service, wage” to the 15th century, and Cardoso (1569) renders soldo with Latin stipendium.[2][13] For Spanish, Corominas explains that the pay of a mercenary was for a time one sueldo, so that the coin's name came to mean his pay.[8] Barbosa (1611) defines it as what is given to the soldier and records soldo á livra “pro rata”.[14] In Brazil it is now the basic pay of the military, to which allowances are added.[15][16] It also named the French sou, the twentieth of a franc.[2][15]
