What is the difference between a curse hex and jinx in Harry Potter?

Answer 1

A curse is something really bad and its effects normally last quite a long time. Hexes are less permanent. Jinxes are just small.

Answer 2

In Harry Potter, a curse is a spell intended to cause harm or injury, a hex is a spell that causes misfortune or discomfort, and a jinx is a spell meant to annoy or inconvenience. While curses are dark magic and can have severe consequences, hexes and jinxes are usually less harmful but still considered dark magic.
