It is not unusual for words to acquire and lose meanings over time, and riddle is no exception. Old English speakers—who had a variety of spellings for riddle, including hrædels, redelse, and rædelse—used the word as we do today to describe a question posed as a problem to be solved or guessed, but they also used it in the now obsolete senses of "counsel," "consideration," "debate," "conjecture," "interpretation," "imagination," and "example." (Not surprisingly, the Old English source of riddle is a cousin to Old English rǣdan, meaning "to interpret" or "to advise.") By the beginning of the 15th century riddle acquired the sense of "a puzzling or perplexing thing," and in the 17th century it also came to refer to "a puzzling or enigmatic person or being."
