Niinja

Niinja is a misspelling of the word "ninja." Ninjas were covert agents or mercenaries in feudal Japan. They were skilled in espionage, sabotage, infiltration, assassination, and guerrilla warfare. The ninja's role contrasted with the samurai, who adhered to a strict code of honor and typically engaged in open combat.

While commonly depicted in popular culture as highly visible, uniformly dressed warriors, historical ninja primarily operated in the shadows. They used stealth, disguise, and specialized tools and weaponry to achieve their objectives. Their activities were often clandestine and their methods pragmatic.

The historical reality of the ninja is often obscured by legend and folklore. While some details of their practices are well-documented, others remain subject to speculation and debate among historians. The association of ninja with supernatural abilities is largely a product of fiction and romanticized accounts.

Today, the term "ninja" is frequently used figuratively to describe someone who is skilled at stealth, secrecy, or working behind the scenes, often in a business or technological context.
