Etymology
It is borrowed from Late Latin theōria (“speculative inquiry”), from Ancient Greek θεωρία (theōría, “contemplation, speculation”).[1][2][3] The DLE and the DCECH derive it directly from the Greek word.[4][5]
The Greek noun is formed from θεωρός (theōrós, “spectator”), which first meant an envoy sent to consult an oracle or to attend a religious festival.[1][2][6] The noun itself first named such an embassy, then the watching of a spectacle.[6] From Plato on it meant contemplation and abstract speculation.[6][2] Corominas connects it with θεάομαι (theáomai, “to look at, contemplate”), the source of teatro, and Wiktionary analyses the word for “spectator” as θέα (théa, “sight, view”) and ὁράω (horáō, “to see”).[5][7][1]
The same learned word is French théorie, borrowed in the late 14th century.[8]
Earliest recorded meaning
The earliest real record in the CDH is in Hernando de Talavera's Católica impugnación (1487): como saben los que algo leyeron de la teoría de la astrología, “as those know who have read something of the theory of astrology”.[9] The CDH's apparently older hit, dated 1356, is in a modern explanatory note on behetría printed with the Fuero viejo de Castilla.[9] The DCECH has its first record about 1580 in Fernando de Herrera, and says that the word was rare until the classical period, when the noun teórica (1399), the feminine of teórico, was more common.[5][7]
Semantic evolution
In the 16th and 17th centuries teoría was set against practice: in 1506 a physician writes that he wants to be useful to health rather than show his learning with teorías, and Correas (1625) opposes teoría o considerazion to pratica o exerçizio.[9] The Academy's dictionary of 1817 still sends the reader from teoría to teórica.[10] By 1899 it had its modern definitions, speculative knowledge apart from any application and a series of laws that relate a class of phenomena, with the Greek sense of a religious procession.[11]
The DLE adds a hypothesis whose consequences apply to a whole science, and the phrase en teoría, “without having been tested in practice”.[4] Moliner notes that in religion one says doctrina, not teoría.[12]
