Forms
tenebrae f pl (genitive tenebrārum); first declension[1]
Etymology
It continues Proto-Italic *temasrā- (“darkness”), the feminine of an adjective Proto-Indo-European *temH-s-ro- (“dark”), with /m/ dissimilated to /n/ before /b/.[2][1] Cognate with Sanskrit तमिस्रा (támisrā, “dark night”) and Old High German demar (“twilight”).[2][3]
Earliest recorded meaning
De Vaan dates it from Plautus, where a character says it was dark “as in a well”.[2][3] Köbler dates Plautus c. 250–184 BC.[4]
Semantic evolution
It was darkness, the absence of light, and the darkness of blindness or death.[3] Figuratively it was mental darkness or ignorance, obscurity or concealment, and a dark or gloomy state of affairs, as the “fog and darkness” that covered the state in Cicero.[3] Isidore says darkness is nothing but the absence of light.[5]
In the medieval Church Tenebrae were the matins of the last three days before Easter.[6] Its derivative tenebrōsus gave English tenebrous in the late 15th century.[7] It survives in Italian tenebre and Spanish tinieblas.[1]
