Forms
mejor m or f (masculine and feminine plural mejores)[1] Old Spanish also wrote meior, meyor, mellor, millor, mijor and miyor;[2][3][4] García de Diego explains the forms with i in the Cid by the influence of peyor “worse”.[2][3][4] Asturian has meyor and miyor, Aragonese and Navarrese millor;[4][5] Judaeo-Spanish has mijor.[4][5]
Etymology
It is inherited from Latin melior (“better”), the comparative used with bonus (“good”), continuing the Latin accusative.[6][7][8][1][9] The same word is Portuguese melhor, Galician mellor, Catalan millor, Occitan melhor, French meilleur and Italian migliore;[10][1] Corominas calls it common to all the Romance languages of the West.[6][10][1] French meilleur likewise comes from the accusative, which ousted the old nominative mieldre.[11]
Wiktionary derives melior from Proto-Indo-European *mélyōs, from *mel- (“strong, big”), and the OLD and the DHLF connect it with multus (“much”), so that the first sense would have been “bigger, stronger”.[1][12][11] De Vaan calls the etymology weak: Ancient Greek μάλα (mála, “very”) and μᾶλλον (mâllon, “more”) show no e-grade, and he mentions as an alternative a link with μέλω (mélō, “to be a concern”) and Hittite māl (“mind”).[13]
Earliest recorded meaning
The first record is in the Cantar de mio Cid (c. 1140, known from a 14th-century copy), where it is an adverb: Doña Jimena prays „cuanto ella mejor sabe” “as best she knows how”.[14][6] The Auto de los Reyes Magos (c. 1180) has the adjective: „los meiores que nos auemos” “the best that we have”.[14]
Semantic evolution
Alfonso X's Lapidario (1250–1279) uses the word both as the comparative of bueno and as the comparative of bien.[15] Covarrubias (1611) called it the irregular comparative of Latin bonus.[16] Autoridades gave the adjective “superior to another thing in some natural or moral quality”, the adverb “more rightly, more justly”, and the phrase mejor te ayude Dios, used to reply that what someone has said is false or ill-meant.[17]
The Academy's dictionary of 1843 adds mejor que mejor “so much the better”.[18] In 1869 a lo mejor was a familiar phrase announcing an unexpected and usually unwelcome event; today it means “perhaps”, and Mexico also says a la mejor.[19][8][20] The edition of 1884 adds the adverb of preference, illustrated by „mejor quiero pedir limosna que cometer una villanía” “I would rather beg than do a base deed”.[21] The pleonastic más mejor is popular in Mexico, Central America, the Caribbean and the Southern Cone, and Alcalá Venceslada recorded it in Andalusia.[20][22]
