Ill-omened is a term used to describe something that is seen as a bad omen or an indication of misfortune. It is composed of three words: ADVERSE (7 letters), DIRE (4 letters), and Sinistrous (10 letters). ADVERSE means unfavorable or hostile, DIRE means extremely serious or urgent, and Sinistrous means ominous or foreboding. Together, these words create a powerful image of something that is seen as a sign of impending doom.
