"Very good; Addams, you are quite right- timing is a critical factor, certainly. Two points for everyone who shared an opinion. And your questions are valid, Miss Greingoth. The answer is actually quite subjective; it is a matter that many scholars have debated for centuries. Some countries, such as wizarding Britian, state that hexes are shorter in duration or intensity than jinxes as a whole, while others such as Romania classify the milder harmful incantations as 'jinxes'. As far as this class is concerned, we will use the classification according to the Ministry of Magic and call the mildest harmful spells 'hexes', though honestly it is all semantics. I am a pragmatist. I do not care what you consider them as long as you know what each individual hex or jinx is and know how to defend yourself. Now... Who can give me an example of a jinx and tell me what it does? And I want to hear from both those who have answered before and some new voices, please." Professor Kazimeriz scanned the room; anyone who was not paying attention did so at their own peril.
