Forms

melhorar (first-person singular present melhoro, first-person singular preterite melhorei, past participle melhorado)[1] Old Galician-Portuguese wrote both melhorar and mellorar.[2][3]

Etymology

It is inherited from Late Latin meliōrō (“to improve”), written Old Galician-Portuguese melhorar and Old Galician-Portuguese mellorar in the oldest texts.[2][3][1] The Late Latin verb is formed from Latin melior (“better”).[2][4][1] Latin /lj/ became the palatal /ʎ/, written ⟨lh⟩ or ⟨ll⟩, as in melhor.[2][3]

The same Latin verb is Galician mellorar, Spanish mejorar, Catalan millorar, Occitan melhorar and Italian migliorare.[5][1] Portuguese and Spanish medrar “to thrive” is another outcome of the same Latin verb.[5][6][1]

The Latin adjective served as the comparative of bonus (“good”).[4] De Vaan reconstructs Proto-Indo-European *mel-iōs and compares Greek μάλα (mála, “very”), but calls the etymology weak, since words for “good” are often renewed.[7]

Earliest recorded meaning

Houaiss and Cunha date the verb to the 13th century.[2][3] In the cantigas d'amigo it means “to make better” and so “to forgive an offence”: Martin de Padrozelos has se de mi queixum' avedes, / por Deus, que o melhoredes “if you have a grievance against me, for God's sake forgive it”.[8][9] A cantiga of Afonso X has se o m'eu melhoro, faço ben “if I make it better for myself, I do well”.[8]

Semantic evolution

Barbosa (1611) has the verb both for “to make better” and for “to get better”, and melhorar na doença “to recover from an illness”.[10] Bluteau (1712–1728) adds a legal sense: melhorar no testamento a child is to leave that child a larger share of the inheritance, within what the law allows.[11] Morais (1789) records it for trade and farming, and for being promoted to a better post.[12]

Today the verb also says that the weather clears up or calms down.[2][13] The derivatives melhora “improvement in health” and melhoramento go back to the medieval language.[3]
