Etymology
Origin of misconduct
Explanation
Misconduct is any kind of bad, unethical, or illegal activity. When there's misconduct, someone is doing something wrong. Since conduct is behavior, misconduct is behavior that's not quite right: some kind of shady or criminal conduct. If an accountant cooked the books — lied about finances — that's misconduct. A police officer taking a bribe is guilty of misconduct. Often, misconduct specifically refers to someone who does improper things on behalf of someone else, like the misconduct of a dishonest lawyer.
