A jinx refers to a spell or charm that brings about misfortune or bad luck. It's often considered unintentional or accidental, unlike a hex, which is intentionally cast to cause harm. The term can also be used to describe a person or situation that seems to be perpetually plagued by bad luck. While a jinx is generally seen as negative, remember, in witchcraft, power lies in intent. So, always aim to bring positive energy into your practice and surroundings.
