Forms

prometer (first-person singular present prometo, first-person singular preterite prometi, past participle prometido)[1] Old Galician-Portuguese also had the metathesised pormeter (1344 pormetemos), and an old past participle prometudo.[2][3] Houaiss records prometter and promity in the 15th century;[2][4][1] prometter was still the spelling of the 19th-century dictionaries.[2][4][1]

Etymology

It is inherited from Latin prōmittō (“to send forth; to promise”), already written Old Galician-Portuguese prometer in the 13th century.[2][5][6][1] The Latin verb is made of prō- (“forth”) and mittō (“to send”), and its first sense was “to send or throw forward, let grow”, from which came “to offer, put forward” and “to give one's word”.[7][2][8] The medieval variant Old Galician-Portuguese pormeter has the r moved, and García de Diego records it in Galician.[2][3][9]

The same Latin verb is Spanish prometer, Catalan prometre, French promettre and Italian promettere.[10][1] The DHLF considers the French word an early borrowing from Latin, reshaped after French mettre.[11] The Latin base verb probably goes back to *meitō and *meyth₂- (“to exchange, remove”).[1]

Earliest recorded meaning

Lorenzo's chronology gives a document of 1261, et prometendóó a mostrar e a prouar “and promising to show and prove it”, and one of 1266, prometo que nunca... seyan enbargadas “I promise that they shall never be impeded”.[3] The Cantigas de Santa Maria tell how the Virgin took the ox that a villager of Segovia ll'avia prometudo “had promised her”.[3] The sense is “to give one's word, vow”.[3]

Semantic evolution

Medieval texts use the verb for vows as well as promises: in the Cantigas someone prometera por en romaria yr “had promised to go on pilgrimage for it”.[3] Barbosa (1611) has prometimento de casamento “promise of marriage”.[12] The sense “to foretell, augur”, with a thing as subject, is in the 16th-century poetry Vieira quotes, where the stars and planets prometiam disaster to a ship.[4] The original Caldas Aulete has “to give hope of, be likely to”, and Houaiss the intransitive “to show promise”.[13][2]

The set phrase prometer mundos e fundos means to make extravagant promises.[14] The DLP records the informal prometer “to threaten to hit someone”.[15]
