Vancian Magic is the common magic system used in most editions of D&D. You can go to almost any design circle who is familiar with D&D and use the term with most people immediately understand to what you refer. I find myself unable to describe other magic systems without describing the system in detail: there are no shorthand or pre-established identifiers for non-vancian systems that I know of.
My question is: are there common descriptions or language to describe magic systems without reference to Vancian Magic? Simply naming the categories of magic as "vancian" and "non-vancian" are not enough. (It's like describing all life in terms of plant or not-plant!)
