The term "caliginous" is artfully employed in literature to evoke a sense of somber mystery and brooding atmosphere. In one instance [1], it colors the description of a head-dress, lending it a nearly tangible aura of gloom that amplifies the gravity of the scene. In another usage [2], the adjective transforms an ordinary collection into something shrouded in an almost conspiratorial darkness, thereby intensifying the mood with an ironic twist. Such applications reveal the word’s versatility in enhancing both visual and emotional textures in narrative settings.
