A double agent is a person who pretends to work as a spy for one country or organization while actually working for another. The term is derived from the French word "double" meaning "double" and "agent" meaning "agent" or "spy". In Hebrew, the term is translated as "סוכן כפול" (sokhen kful). In Spanish, it is "agente doble", in German "Doppelagent", and in Russian "двойной агент" (dvoynoy agent). Double agents are often used to deceive the enemy, gather intelligence, or spread disinformation. They play a crucial role in espionage and counterintelligence operations, as their ability to operate undetected can provide significant advantages. However, the use of double agents also carries risks, as their true loyalties can be difficult to verify, and they may be discovered or turn against their handlers.
