The word "rogue" refers to a person who behaves in a dishonest or unprincipled way. It can also denote an individual who is mischievous or playfully dishonest, often breaking rules or norms but in a way that is not necessarily harmful. Additionally, "rogue" can describe something that is detached or separate from a larger group, often behaving unpredictably.
The word "rogue" originates from the early 16th century, deriving from the Middle English word "rogue" meaning "a beggar" or "vagabond." It is believed to have come from the late Latin word "rogare," meaning "to ask." Over time, the meaning evolved to imply a person who behaves outside the norms of society.
