Etymology and origin of the French word obscur
From the same root
Pronunciation
- /ɔp.skyʁ/[1]
Forms
obscur (feminine obscure, masculine plural obscurs, feminine plural obscures)[1] Old French oscur (late 11th century), obscur from the 12th century;[2][3][4] oscur remained the usual form until the 16th century and is still found in Ronsard.[2][3][4] Anglo-Norman also had escur and ouscur.[5]
Etymology
It is borrowed from Latin obscūrus (“dark, gloomy; hard to understand; unknown; hidden, secret”).[6][2][3][7] It was first written oscur, with the Latin ⟨b⟩ restored in the 12th century;[2][8] Wiktionary instead treats the word as inherited through Old French, the ⟨b⟩ coming from a learned relatinisation in Middle French.[1] In the 16th century it was still pronounced ⟨oscur⟩, according to Théodore de Bèze.[9]
The Latin word has no clear analysis;[2] Rey reports a proposal that it contains an element *-scūrus related to words for shade and cover, such as Old Norse skuggi (“shadow”), Old High German scuwo (“shadow”) and, through Norse, English sky.[2] Littré connected the same conjectured element with Latin scūtum (“shield”), so that the word would mean “covering all round”.[9] Its semantic opposite in Latin was clārus, the source of clair.[2]
Earliest recorded meaning
It is first found at the end of the 11th century in the Chanson de Guillaume, spelled oscur, meaning “without light, dark”.[4][2] The TLFi's first record of this sense is in the Roman d'Eneas (about 1160).[6]
Semantic evolution
In Old French the adjective was already used as a noun, l'oscur, for darkness (1160–1174, Wace), and of a dark colour (about 1165, Benoît de Sainte-Maure); in the colour sense it lost ground to sombre and foncé after the 17th century.[6][2] As a painters' term l'obscur is the dark part of a picture (1690, Furetière), as in clair-obscur.[6][2]
The figurative sense “hard to understand” is as old as the physical one (1160–1174, Wace).[6][2] In the 16th and 17th centuries the word came to mean “unknown, without renown” (1559, Amyot) and “of humble birth” (1611, Cotgrave), and the Port-Royal Logique (1662) used it actively of a person who understands poorly, a sense now lost.[6][2] Salles obscures for cinemas dates from 1917.[4][2]
