Forms
mejorar (first-person singular present mejoro, first-person singular preterite mejoré, past participle mejorado)[1] Old Spanish wrote meiorar, and 16th-century texts from the Americas mexorar.[2][3]
Etymology
It is inherited from Late Latin meliōrō (“to make better”), a verb formed from melior (“better”).[4][1][5] Corominas and Gómez de Silva instead treat it as a Spanish derivative of mejor with the verb ending -ar, and Wiktionary notes the same analysis.[6][7][8][1]
The Latin verb continues in Portuguese melhorar, Galician mellorar, Catalan millorar, Occitan melhorar and Italian migliorare.[1][9][5] French améliorer was remade in 1507 after the Latin comparative from Old French ameillorer.[10] Spanish medrar “to thrive”, used by Berceo, is according to Corominas a reduced form of this verb through a stage *mejdrar; the REW places it directly under the Latin verb.[6][9]
De Vaan reconstructs the Latin comparative as *mel-iōs but calls the etymology weak, since the Greek cognate he cites, Ancient Greek μάλα (mála, “very”), shows no trace of an e-grade.[11]
Earliest recorded meaning
The BDELC dates the verb to 1107.[7] In the Cantar de mio Cid (c. 1140, in a 14th-century copy) the hero's men rejoice: ya mejoraremos posadas a dueños e a cavallos “now we shall find better lodgings for masters and horses”.[12][6]
Semantic evolution
In the prose of Alfonso X and his school the verb already meant to make something better, to get well, and to make good a wrong: the count asks the king of Navarre quel meiorasse los tuertos “to make amends for the wrongs”.[13] In legal use it meant giving an heir more: Covarrubias in 1611 explains mejorar en el testamento as leaving one child a larger share, within what the law allows.[14] The modern dictionary adds the bidder who raises the price at an auction and the weather that improves.[4]
