Forms

estudo m (plural estudos)[1] Old Portuguese wrote studo, estudo and studio.[2][3]

Etymology

It is inherited from Latin studium (“zeal, eagerness; study”), written Old Galician-Portuguese studo and Old Galician-Portuguese estudo in the oldest texts.[2][3][1] The Latin noun is formed from studeō (“to be eager, apply oneself”) with the suffix -ium.[4][1] Its first sense was zeal or eager application to anything; since those who gave themselves to intellectual work did so with great application, the word came to mean study.[5]

Meyer-Lübke lists the Portuguese word among the learned forms of the Latin noun, beside Spanish estudio, Catalan estudi, Italian studio and French étude.[6] Nascentes reports that Carolina Michaëlis set up an intermediate form Old Galician-Portuguese estuido.[7] The literary Galician form is estudo, but people say estudio, already found in the medieval General Estoria.[8]

Earliest recorded meaning

Houaiss dates the form studo to the 13th century.[2] In 1309 King Dinis wrote of “the masters and scholars of my studo of Coimbra”, that is, of the university.[8] Medieval Latin studium had the same sense of school or university.[8][9] The Galician-Portuguese Crónica Geral tells of daughters sent to the estudos of noble ladies to be better taught.[8]

Semantic evolution

The medieval texts use the word both for the school and for the effort of learning: a document of 1436 speaks of the protector of the estudos de Portugal, and the Imitação de Cristo of the care and thought given to the life of Christ.[8] Cardoso (1569) translates casa de estudo with Latin musaeum, and Folqman (1755) gives both the school where grammar is taught and application to study.[10][11] Morais (1813) still records the older senses “care, diligence” and “love, affection”.[12] Figueiredo (1899) adds the musical study, written as an exercise, and the sketch made before a work of art.[13] The plural estudos means one's schooling.[14][2]
