Etymology

Origin of rogue

First recorded in 1555–65; origin uncertain, apparently short for obsolete roger “begging vagabond,” originally thieves' jargon

---

Explanation

A rogue is a sneaky person who has tricks up his sleeve, not like a magician, but like someone who would steal your wallet or cheat at cards. Dishonesty won’t get you far in life, unless you are a rogue who survives by lying and exploiting others. The word comes from the Latin rogare, which means “beg,” and while some rogues dress like beggars to get your money, anyone who deceives is a rogue, like the presidents of corrupt corporations who steal from their employees, or that rogue Uncle Marvin who promises you chocolate for washing his car, but afterward tells you he has no chocolate. That rogue!
