An insignia (Latin: īnsignia, nominative plural of insignium, "emblem, token, symbol"), plural insignias, is a symbol or token of personal power, status or office, or of an official body of government or jurisdiction. An insignia is usually the emblem of a specific or general authority.
Official insignia are often protected by law as to allow their use only by people holding a specific office or staff members acting on behalf of such a person. Misuse, defacement and destruction of such symbols is considered an offense in many countries.
