Mynoreteh
A reversed heteronym. A word or phrase becomes another when reversed. Examples: won ton, not now; or ONE = barcarole’s summer—aha!, TWO = a harem, mussel, or a crab.
Unlike most flat types, a mynoreteh needn’t have dictionary nature; indeed, at least one part must not, otherwise the puzzle would be called a reversal (which see) instead.
The mynoreteh was introduced by Ulk in 1990.
