Forms

diplomate m or f by sense (plural diplomates)[1]

Etymology

It is a back-formation from French diplomatique (“diplomatic”), made on the model of the pair aristocratique and aristocrate.[2][3][4][5][1] That adjective is from New Latin diplomaticus, used in 1681 in the title of a treatise by Mabillon, from Latin diplōma (“charter, official document”).[4][5] The Latin word comes from Ancient Greek δίπλωμα (díplōma), properly a sheet folded in two.[5][1][6] Littré explains that the diplomat was so named because diplomas are acts issued by princes.[7]

Earliest recorded meaning

It is first found as an adjective in 1789, in the Mémoires of the Baroness of Oberkirch, in the figurative sense “skilful in dealing with people”.[8][4]

Semantic evolution

The literal sense followed at once: in 1792 the adjective meant “charged with a mission to a foreign government”, and the noun appeared the same year in the title of a journal, Le Cosmopolite, ou le Diplomate universel.[8][4] The GLLF cites the noun for an official representing his country from 17 May 1792, in le Défenseur de la Constitution.[3] The derivative diplomatie followed in 1791, on the model of aristocratie.[5]

Used of anyone who can handle a negotiation with tact, the noun is recorded by Boiste in 1839.[3] In the 20th century diplomate became the name of a cold dessert served with a fruit sauce, first in Proust (1922),[8][4] by the habit of naming a dish after a prestigious diner, as in vol-au-vent financière.[4] The Wiktionnaire reports that the dessert is said to have been devised by Montmireil, Chateaubriand's cook, when Chateaubriand was a diplomat in London in 1822, and that the name is short for pudding à la diplomate.[9]
