Avenge is the act of doing something to hurt another person in the sense of achieving justice because that party caused harm to someone; to repay: “Sam wants to avenge and to punish the person who caused his mother’s injuries.” / “Salman planned to avenge his brother’s death by burning the murderer’s house down.”
Revenge, on the other hand, usually stresses reprisal for the person wronged or offended; to pay back: “He still plans to revenge the injury done to him by getting even.” It is an action taken in return for an injury or harmful offense: “They humiliated me, but I will get my revenge.”
