Forms
protocolo m (plural protocolos)[1] Houaiss records portacolo in 1712, protocollo in 1720 and protocolo in 1836.[2] Bluteau heads the word protocollo and notes the popular form portacollo.[3] The REW cites an old Portuguese protacolo.[4]
Etymology
It is borrowed from French protocole, according to Houaiss, Cunha and Nascentes, and the French word is from Medieval Latin protocollum.[2][5][6] The DLP and Vieira derive it directly from the Medieval Latin word, as Figueiredo did according to Nascentes, and the early spellings of Bluteau's time show the notarial word before the French diplomatic senses arrived.[7][8][9][3] In the computing sense the DLP takes it from English protocol.[7]
The Medieval Latin word meant a notary's record from 945, an original deed from 1166 and a chancery register from the 14th century.[2][10] The French word is recorded from 1330.[2][10] It is πρωτόκολλον (prōtókollon), the first sheet glued to a papyrus roll or charter, on which its contents and marks of authenticity were written.[6][11][1] The Greek compound is made of πρῶτος (prôtos, “first”) and κόλλα (kólla, “glue”).[2][1] The same Latin word is Italian protocollo and Spanish protocolo.[4]
Earliest recorded meaning
Cunha dates the word to the 17th century, and Houaiss's first record is from 1712.[5][2] Bluteau's dictionary explains it as the book in which a notary first writes down his deeds.[3]
Semantic evolution
Morais (1789) also has the book in which court officials record the handing over of case files to lawyers.[12] According to Nascentes, the modern senses “preliminary memorandum” and “rules of etiquette in official ceremonies” grew up in France and spread with the dominance of French after the Peace of Nijmegen (1678).[6] French records the record of a diplomatic conference in 1823 and diplomatic protocol in 1859.[2] Vieira already describes the protocol of a diplomatic conference.[8] In Brazil the word also names the office that registers incoming documents and the receipt it issues.[2] The computing sense, a set of rules for data transmission, is the most recent.[2][7]
