Omen

An omen (also called portent or presage) is a phenomenon that is believed to foretell the future, often signifying the advent of change. Though the word "omen" is usually devoid of reference to the change's nature, hence being possibly either "good" or "bad," the term is more often used in a foreboding sense, as with the word "ominous". The origin of the word is unknown, although it may be connected with the Latin word audire, meaning "to hear."
