Forms

alumiar (first-person singular present alumio, first-person singular preterite alumiei, past participle alumiado)[1] Old Galician-Portuguese wrote alumẽar, alumear and alumiar, and the 14th century also alomear and alomyar.[2][3][4]

Etymology

It is inherited from Vulgar Latin *allūminō (“to light, kindle”), written Old Galician-Portuguese alumẽar in the oldest texts.[3][5][6][7][1] The REW and Machado explain the Vulgar Latin verb as a remodelling of illūminō (“to light up”), and Houaiss and the DLP derive it from lūmen (“light”).[6][4][3][7] Nascentes, Aurélio and Vieira start from the classical verb itself, and Nascentes reports that Cornu saw the influence of the ⟨l⟩ there, while Meyer-Lübke preferred the Vulgar Latin form.[8][9][10] Vieira points to the loss of the medial /n/, as in sēminō > semear.[10]

The same Vulgar Latin verb is Galician alumear, Spanish alumbrar, Old Occitan alumenar, French allumer and Italian alluminare.[6][1] The Latin noun goes back to *léwk-s-mn̥, from the root *lewk- (“bright”).[11][1]

Earliest recorded meaning

In the Cantigas de Santa Maria a great light is seen que alumeava mui mais que outras craridades “that shone far more than other lights”, and one cantiga tells how Holy Mary gave sight to a blind cleric (alumiou un crerigo que era cego).[2] The Miragres de Santiago use it for healing the blind as well as for giving light.[12]

Semantic evolution

The medieval senses, “give light” and “give sight to the blind”, led to the spiritual sense: a 14th-century catechism says that faith alomea o entendimento “enlightens the understanding”.[4][12] Bluteau adds “to walk before someone with a torch”.[13] Morais (1789) records a farming sense, to open furrows in ploughed land to drain it, and an engraver's term, to fire the letters cut in stone and filled with pitch to blacken them.[14] Figueiredo (1899) has the Algarve sense “to dig round the trunk of a vine to give it more light”, which Houaiss gives as regional Portuguese.[15][3]

Brazilian Portuguese uses it intransitively for “to gleam, shine”, and the informal sense “to proclaim, make known” is in Houaiss and the DLP.[3][7][16]
