illuminer[1]
Etymology
It is borrowed from Latin illūminō (“to light up, adorn, make famous”), borrowed about 1200.[2][3][4] In Christian Latin the verb also meant “to give sight to”, “to instruct” and “to enlighten the soul by grace”.[2][3] It is formed from in- and lūmen (“light”),[3][4][5] which Rey derives from a form *leuk-s-men, from Proto-Indo-European *leuk- (“to be bright”), the root also of lūx.[3] The verb enluminer goes back to the same Latin word.[2][6][1]
Littré compares Old Occitan illuminar, Spanish iluminar and Italian illuminare.[7]
Earliest recorded meaning
About 1200 the Dialogues of Saint Gregory use illuminer les avogles, “to give sight to the blind”, the sense of Christian Latin.[2][3][5]
Semantic evolution
About 1350 Gilles li Muisis used it for giving out light and for enlightening someone with divine truth.[2][3] Oresme wrote that la lune est illuminée du soleil, “the moon is lit by the sun”.[7] From the 14th to the 17th century it was also used in the sense of enluminer, to illuminate a manuscript, as when La Boétie speaks of livres illuminez.[3][7] In 1694 the Académie records its use for decking a building or a street with lights for a festivity.[2][3]
The past participle illuminé meant “intelligent” in 1564; as a noun it named an enlightened mind and, in the history of religions, a mystic believing in inner illumination (1625), then a visionary (1690).[3][2] From 1791 it was also said of a person who blindly follows his inspirations.[3]
