ténébreux (French)
Where does "ténébreux" come from?
The French word 'ténébreux' was borrowed around 1100 from the Latin 'tenebrōsus', which originally described something full of darkness. Its root traces back to the Proto-Indo-European word for dark, 'temH', combined with a suffix that may have anciently meant 'smelling like'. Over time, the word evolved from describing physical shadows and night to characterizing a person's moody or mysterious temperament.
