Etymology

It is borrowed from Medieval Latin protocollum (“first sheet of a document; notary's register”), which the DLE calls Late Latin.[2][3][4] The Latin word is from Ancient Greek πρωτόκολλον (prōtókollon), a late, Byzantine Greek word for the sheet glued to the front of a document to authenticate it, literally “the thing glued first”.[5][2][6] It is formed from πρῶτος (prôtos, “first”) and κόλλα (kólla, “glue”).[5][1]

The Greek word occurs, beside the Latin one, in the translation of Justinian's Code of the 6th century; in Medieval Latin it meant the minute of a contract and the register of a notary's minutes.[7][8] The same word is Italian protocollo, French protocole and Portuguese protocolo, with an Old Portuguese variant Old Galician-Portuguese protacolo.[9]

Covarrubias in 1611 took the second part instead from a Greek word for “limb”, because the book was a member of the act.[10]

Earliest recorded meaning

The earliest record in the CDH is a notarial document of 1456–1457, which says that a notary avia subçedido en los registros e protocolos, “had succeeded to the registers and protocols”, of his father, also a notary.[11] Corominas dates the word only from 1611, and Nebrija's Latin dictionary of 1492 already translates Latin protocolum as el protocolo de notario.[5][12]

Semantic evolution

For three centuries the word meant the notary's book of registers: Covarrubias calls it the original book of public acts, and the Diccionario de Autoridades the book in which a notary keeps the registers of the deeds he has drawn up.[10][13] Domínguez in 1846 added the code of etiquette by which governments deal with one another and the register of the decisions of congresses; the Academy took in the record of a diplomatic congress in 1869.[14][15]

The modern dictionaries add the rules for official ceremonies and, by extension, of courtesy, the detailed plan of a scientific or medical procedure, and the rules for the exchange of data between computer systems.[2][16][6] In medicine the word is recorded from 1832, and Puerto Rican Spanish uses the computing sense under the influence of English protocol.[4][17] In Guatemala and Panama it also names the group of people who receive the guests of a congress, and in Nicaragua, jokingly, a big belly.[18]
