NEMO backwards is OMEN.


An omen (also called portent or presage) is a phenomenon that is believed to foretell the future, often signifying the advent of change.[1] 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."
