Raising devil is a common phrase used to describe a mischievous or troublesome person, but there are several synonyms that can be used in its place. One such synonym is "troublemaker," which implies that the person is intentionally causing problems and disruptions. Another option is "rabble-rouser," which suggests that the person is attempting to stir up trouble or incite a reaction from others. "Mischief-maker" is also a suitable synonym for raising devil, as it describes someone who enjoys causing minor disruptions or playing harmless pranks. Other options include "scamp," "imp," and "rascal," all of which convey a sense of cheeky mischief-making.
