Etymology: The adjective in question appears to be a variant or a mistaken form related to the Latin-derived English adjective "nefarious," which means wicked or villainous. The Latin root is "nefastus," a term used in ancient Rome to describe days that were considered unlucky or unlawful for public business, derived from "ne-" meaning "not" and "fas," meaning "divine law" or "right." Thus, "nefastus" literally conveyed a sense of being contrary to divine law, improper, or ill-omened. "Nefastus" itself is a classical Latin adjective that was used to mark days on the Roman calendar when certain activities, especially legal or political ones, were forbidden. This meaning was more about the calendar and the idea of taboo or prohibition rather than moral wickedness. Over time, the concept of something being "nefastus" as forbidden or ill-omened evolved in English through "nefarious," which shifted the focus from the calendar to character and actions, emphasizing moral evil or criminality. The form "nefastous" is not standard in English and likely stems from a blending of "nefastus" and English adjectival endings like "-ous," which form adjectives meaning "full of" or "characterized by." It may arise from an attempt to align the classical Latin root more closely with English morphological patterns, but it remains rare or nonstandard. The correct and historically attested English adjective remains "nefarious." In summary, the root traces back to ancient Roman religious and legal customs, with "nefastus" marking forbidden times. The moral dimension came later with "nefarious," which inherited the sense of violation of divine or natural law but applied it to human behavior. The variant "nefastous" is a modern, nonstandard form that attempts to revive the older Latin structure with an English adjectival suffix but did not enter common usage.
