The word "guilty" refers to the state of having committed a crime or offense, or feeling a sense of regret or remorse for an action or wrongdoing. When someone is described as guilty, it often implies that they have been found responsible for an act that is considered wrong, whether it be a legal matter or a personal moral failing.
The word "guilty" originates from the Old French word "guilte," which means "fault" or "offense." This, in turn, traces back to the Proto-Germanic word "*gabiliz," meaning "to give" or "to owe," reflecting a notion of owing a debt for wrong actions.
