Etymology

The word "ominously" derives from the Latin root omen (meaning "a sign or portent"), combined with the suffix -ous (forming adjectives) and the adverbial suffix -ly. The original Latin omen often carried a supernatural connotation, implying a divine warning. Over time, "ominous" evolved in English to describe anything that hints at impending danger or misfortune. The addition of -ly transforms it into an adverb, emphasizing the manner in which such foreboding is conveyed.
