[Harry Potter] What is the difference between a jinx, a hex, and a curse?
gpt
Curses are the worst of the three, and are intended to cause lasting damage to the sufferer. There is also no generalised "anti-curse" or "curse removal" spell, unlike the other two, although it is possible to block or redirect most of them (with the exception of the Killing Curse) if you recognise what you're dealing with fast enough.

Hexes are the middle group, which generally causes major discomfort but not lasting damage. The effects are permanent until removed by the "Hex Breaker" spell, which works on all known Hexes. 

Jinxes are the weakest of the three. They are not permanent,  and can blocked with a Counter-Jinx. In a combat situation, they are generally used as tactical spells to gain a momentary advantage, such as the Trip Jinx.
