moonlighting

• Allan Metcalf, in Predicting New Words, cites a study that found that while more than half of all new words result from making compounds (two complete words joined together, such as moonlighting) or adding prefixes or suffixes (such as shopaholic), "blends that use just parts of words rarely succeed, accounting for only about 5 percent of new words."
