Although most ponies outside of researchers or spell scribes don't use or really know these terms as it's mostly for somepony doing spell creation. Speaking of spell creation, I've found some texts about it in the small library at the orphanage mostly in warnings about its dangers because you can get hurt when a spell becomes unstable this danger and the difficulty most ponies seem to have with more complex math makes spell creation an uncommon career to attain as higher education is needed. This is one of the main reasons that even in an empire as big as Equestria there are only a few real magic schools, most ponies just don't have the talent or drive to try.
