Could someone please post an article defining the types of magic and how they relate to one another?

Here are some of my questions. Would all magic be spells? What makes a Charm a charm and not something else? Are curses separate from spells? Is a hex a weak curse? If not, what distinguishes it from a curse? Is a Transfiguration a type of Charm? Is apparating really a spell? Do you have to say something for magic to be a spell? And so on.

Every time I read anything about Harry Potter I run up against these words and wonder how they relate to each other. I can't find an article on the Wiki that tells me.

Thank you.
