Pronunciation

  • /doɡˈtoɾ/, [d̪oɣ̞ˈt̪oɾ][1]

Forms

doctor m (plural doctores, feminine doctora, feminine plural doctoras)[1] Until the 17th century the word was usually pronounced without the /k/, and Nebrija writes dotor.[2] Old Spanish texts have both doctor and dotor.[3][4]

Etymology

It is borrowed from Latin doctor (“teacher, one who teaches”), a learned word.[2][5][1] The DLE specifies doctor, noting that the classical word meant “teacher”.[6] Vox dates the borrowing to the 13th century.[7]

The noun is formed from Latin doceō (“to teach”) + -tor.[8][1] De Vaan traces doceō to Proto-Italic *dok-eje- and Proto-Indo-European *doḱ-ei̯e/o- (“to make someone accept something”), the causative of the root of Latin decet (“it is fitting”).[9][10]

The same Latin word gave Portuguese doutor, Galician doutor, Italian dottore and French docteur.[1][11] The Latin word is also the source of a group of learned Spanish words from the same verb, among them docto, doctrina, dócil, documento and docente.[2][5]

Earliest recorded meaning

The DCECH's first record is the Libro de Alexandre, where the word means “teacher, master”; it then appears in Juan Ruiz, Don Juan Manuel and other authors of the 14th and 15th centuries.[2] The Tentative Dictionary gives the sense “learned man” in the Libro de buen amor, with doctores philosophos, and in Don Juan Manuel's doctores de sancta eglesia.[3] Alfonso X's General estoria uses it for a learned writer: segund departe un doctor delos frayres menores “as a doctor of the Friars Minor explains”.[12]

Semantic evolution

From “teacher” the word passed to a university degree: a law of 1462 names it as an academic title, though it was used that way earlier.[2] The Diccionario de Autoridades held that the title of doctor was created about the middle of the 12th century to replace maestro, which had become too common to be prized.[13] The Church also gives the title to saints whose writings defend or teach the faith.[13][6]

The sense “physician” grew gradually: in the 14th century Spanish said doctor en medicina, but in the 15th century doctor alone could already mean a physician.[14] Autoridades notes that the physician was popularly called doctor even without the degree, and that some said dotor to tell him apart from doctors of other faculties, a usage it calls a corruption.[15] Today it is the usual way to address a physician.[6][16]

In Spanish America the title spread further: Román complained that in Argentina and other republics it was given to lawyers, and in some to every priest, but not in Chile.[17] In Panama doctor is slang for a drug dealer.[18] In the Spanish of the United States, under English influence, it can mean any specialist or professional.[19] The word passed into Tagalog as doktor.[1]

Timeline

  • 1272–1275 – Alfonso X's General estoria uses it for a learned writer.[12]
  • 1330–1343 – the Libro de buen amor has the form dotor.[3]

  • 1546 – first record in the Americas, in Santo Domingo, of a doctor who worked as physician and surgeon.[20]
  • 1614 – Jiménez Patón still notes the pronunciation without /k/.[2]
  • 1732 – the Diccionario de Autoridades gives the university, Church and popular “physician” senses.[13]
  • 1884 – the Academy's dictionary gives the etymology “Del lat. doctor”.[21]
