"Yes, quite. So."
She pauses, taking a breath, and feeling a tension that she should probably feel starting, stop.
"Magic."
"Magic, in general, is the art of utilizing one of the six primordial forces, or the two composite forces, to affect the world or yourself."
"Today, we're learning Arcane magic, which touches the primordial force of Order - or Meaning, or Definition, or...Well. There are a lot of things it could be." Control, she doesn't add.
"The names we assign to the primordial forces are petty approximations of their natures, which...they are not intended," she says with far more certainty than she really should have about the world, "to be fully comprehensible to any of us mere mortals. But each one has things it is more suited for, and - ways of approaching the magic, that they respond better to."
"Both Arcane magic and its counterpart, chaos magic, sometimes called fel magic for legacy reasons, deal most directly with the Twisting Nether - the primordial chaos that this reality is merely a bubble of stability within."
"Order magic...Hmm. Draws forth a carefully selected partition of the infinite possibility the Twisting Nether represents. Chaos magic...draws forth the energies of the Twisting Nether in much the same way, but does not care so much to constrain which ones - letting the possibilities run wild, in a sense."
"...In other senses, looking at what we pretend is chaos magic is looking at a kiddie pool and calling it the ocean, because in practice chaos magic is all about restraining the magic's degrees of freedom - in the opposite way of order magic, where you start from a framework that permits nothing and broaden its limits until the magic does what you want - but still, with intent to cause the same effect of not having Literally Anything happen. Literally Anything happening is not good for continued existence."
