Pronunciation

  • /pɾomeˈteɾ/, [pɾo.meˈt̪eɾ][1]

Forms

prometer (first-person singular present prometo, first-person singular preterite prometí, past participle prometido)[1] Old Spanish forms include prometo, prometemos, prometió and the old future prometrien.[2][3]

Etymology

It is inherited from Old Spanish prometer, inherited from Latin prōmittō (“to send forth; to promise”).[1][4][5] Corominas dates it to the second half of the 10th century.[6]

The same Latin verb is Portuguese prometer, Catalan prometre, French promettre and Italian promettere.[7][5]

The Latin verb is formed from prō- (“forward”) and mittō (“to let go, send”).[8][9] Its first sense in Latin was “to send forth, let loose”, and in Plautus and later authors it also meant “to undertake to give or do, to promise”.[8] De Vaan explains the simple verb from an original sense “to exchange”, which became “to give, bestow” and then “to let go, send”.[10] Wiktionary traces it, through Proto-Italic *meitō, to Proto-Indo-European *meyth₂- (“to exchange, remove”).[1]

Earliest recorded meaning

Corominas puts the first record in the second half of the 10th century.[6] The Cantar de mio Cid (c. 1140, in a 14th-century copy) has it in the full sense “to promise, to vow”: „A Dios lo prometo, a aquel que está en alto” “I promise it to God, to Him who is on high”.[11][12]

Semantic evolution

In Alfonso X's prose prometer means “to bind oneself to do or give something”, “to vow oneself to God”, “to promise each other in marriage” (Aeneas and Dido promise to take each other as husband and wife) and “to give signs of”, as a planet fulfils what it promises at a birth.[3] Berceo already uses the pairing of promising and giving: „prometer e non dar”.[11]

The Diccionario de Autoridades defined it as offering firmly to do or give something and also as “to assert, assure”, with a quotation from the Partidas on prelates who must not promise benefices before they fall vacant.[13] The Academy's 1884 dictionary added the intransitive sense “to show early promise” (este niño promete) and the colloquial phrase prometérselas felices “to have high hopes on little ground”.[14] Today the intransitive verb is also used of things that show qualities that may make them succeed.[4] The participle prometido became a noun for a person engaged to be married, and promesa is an old participle of the verb.[5][6]
