Not a confusing title at all... Currently if Anne goes to an NPC and buys a Teachable recipe she can learn it from that scroll, then teach it to Bob, Carrol, Damian, all her assorted alphabetical buddies. But because these people haven't learned it from a scroll, and it is only Teachable, not Re-Teachable, they cannot pass it on. It gets forever locked into a Not-Teachable state for them It's a really cool system, but it would also be nice if there was a way to re-learn a recipe taught to you by another, to convert it to a Teachable form. So if Anne teaches Bob he can use the recipe all he'd like, but if he wants to teach someone else he's able to go re-learn it from the NPC scroll and then teach others.
