Forms
diplōma n (genitive diplōmatis); third declension[1] Also duplōma; the grammarians record dipluma and diplōmum.[2][3]
Etymology
It is borrowed from Ancient Greek δίπλωμα (díplōma, “folded paper; licence”), from διπλόος (diplóos, “double”), a letter folded double.[2][1][4][5][6]
Earliest recorded meaning
Lewis & Short and Köbler cite Cicero, of a state letter of recommendation for travellers.[5][4] Köbler dates Cicero 81–43 BC.[4]
Semantic evolution
It was a folded tablet with a magistrate's instructions giving the bearer free passage and help on a journey, as in Cicero and Tacitus; under the Empire it allowed the use of the imperial post, and it was also a letter of recommendation or a certificate of privileges, as in Suetonius.[2][5] An officer ā diplōmatibus issued them for the emperor.[2]
In Medieval Latin it was a decree of a church council and a bill of indictment.[7] British Medieval Latin used it for an official document, especially a papal letter of appointment.[8] In Ecclesiastical Latin it was a diploma, charter.[9] English diploma (1640s, “state paper”) is from it, and New Latin diplōmaticus (1680s) gave English diplomatic, first “of official documents”.[6]
