Forms

esclarecer (first-person singular present esclareço, first-person singular preterite esclareci, past participle esclarecido)[1]

Etymology

It is formed from Portuguese es- + claro + -ecer.[2][1][3][4] Vieira (1871–1874) derived it instead from Latin clārēscō (“to become bright”), and the DLE derives Spanish esclarecer from ex- and the same verb.[5][6] The 13th-century texts also write Old Galician-Portuguese sclarecer and Old Galician-Portuguese escrarecer.[2][7] claro is from Latin clārus (“bright, clear; loud”), which goes back to *kelh₁- (“to call, shout”), the sense “loud” being older than “clear”.[1][8] The Galician verb is esclarecer “to clear up, dawn”.[9]

Earliest recorded meaning

In the Cantigas de Santa Maria the verb means “to light up, make bright” and, intransitively, “to become bright”: the great power of the saints que a terra toda sclareceu “which lit up the whole earth”.[10] Houaiss and Cunha date the forms esclarecer, sclarecer and escrarecer to the 13th century.[2][7]

Semantic evolution

The early dictionaries know only the physical sense: Barbosa (1611) has “to give light, to dawn”, and Bluteau (1712–1728) “to become light”, of the day and of the weather after mist.[11][12] Morais (1813) adds the figurative senses “to enlighten the mind” and “to make noble, illustrious”.[13] The original Caldas Aulete quotes Mendes Leal for “to make understandable, elucidate”, the sense that now prevails, along with “to give explanations to someone” and, in the reflexive, “to inform oneself”.[14][2] The DLP marks the sense “to light up” as little used today.[3]
