doutor m (plural doutores, feminine doutora, feminine plural doutoras)[1] The medieval texts write doutor and the Latin spelling doctor from the 13th century, and douctor and dottor later.[2][3]
Etymology
It is inherited from Latin doctor (“teacher, instructor”), written Old Galician-Portuguese doutor in the oldest texts.[2][3][1] Wiktionary calls it a semi-learned borrowing.[1] The Latin spelling Old Galician-Portuguese doctor stood beside it in the 13th century, with Old Galician-Portuguese douctor in the 14th and Old Galician-Portuguese dottor in the 15th.[2][3]
The same Latin word is Galician doutor, Italian dottore and French docteur, the French one a learned borrowing first recorded around 1150.[1][4][5]
The Latin noun is the agent noun of doceō (“to teach”), formed with the suffix -tor.[6][2][1] In classical Latin it meant a teacher or trainer;[7][8][4] Christian writers used it for an apostle or a Father of the Church.[7][8][4]
Earliest recorded meaning
In the Crónica Troiana the word means a learned man, an author of books: que forõ doutores “who were scholars”.[9] A satirical cantiga addresses someone as doutor, asking what profit a married man finds in caring for his estate.[10]
Semantic evolution
From “teacher” and “learned man” the word passed to the holder of the highest university degree: Barbosa (1611) still glosses it as a preceptor who gives instruction, while Morais (1789) defines it as one who has received the highest academic degree, with the right to wear the tassel and hood and to teach his faculty.[11][12] Nascentes notes that the university degree was created in the 12th century, and that the title stuck to physicians because they, more than other graduates, made the most of it.[13]
By extension it became a courtesy title for any graduate, for judges and magistrates, and above all for doctors of medicine, so that doutor alone came to mean “physician”.[2][14] Figurative and ironic senses followed: a know-all, an old hand at something, often something disreputable.[2][15] In the colloquial language of Portugal a doutor was also a chamber pot.[16][17]
