The phrase "away with you" typically implies a sense of dismissal or rejection. There are several synonyms that can be used instead of this phrase, including "begone," "depart," "leave," "exit," or "go away." Each of these synonyms conveys a similar sense of urgency and insistence that the other person leaves or departs immediately. Other options include "scram," "shoo," "skedaddle," or "git." These more informal synonyms are often used when a person wants to express a sense of annoyance or frustration with the other person's presence. Regardless of the wording used, the message remains clear - it's time to go.
