Adj. 1. nighted - overtaken by night or darkness; "benighted (or nighted) travelers hurrying toward home"

Nighted streets and forests abound in Howard’s tales. This is perhaps his signature term and betokened [a term he uses often, also] not just darkness, but the cold and loneliness of the night, prowled by nocturnal predators and haunted by ancient horrors and primordial fears. With nighted often used to accentuate the depths of an abyss, as in “…up from the knighted abyss.”

For, “the coming of night was a kin to death” narrates Howard in The Devil in Iron.

Thus far, all Micrοsοft Word dictionaries have made an automatic change of spelling to knighted, another straw of diction inflexibility gathering to break our literary back.
