Etymology
The word vicious originates from the Latin word vitiosus, meaning “faulty” or “full of faults,” from vitium, meaning “fault” or “defect.” It entered Middle English via Old French vicios, carrying the idea of moral depravity or corruption. Over time, its meaning expanded to include not only wrongdoing but also cruelty, violence, and aggressive behavior. Today, vicious is widely used to describe both people and animals that act in fierce, dangerous, or brutal ways.
