What is the difference between Hoodoo, Conjure, and Rootwork?
Each of those terms refers back to the same tradition and are simply regional variations. The terms are fluid and apply to the greater body of the tradition while also sometimes referring to the people who practice the system of magick. Practitioners are called Conjures, Conjurers, Conjure Doctors, Hoodooers, Hoodoos, Trick Doctors, Conjure Men/Women, Goofer Doctors, root doctors, rootworkers etc. The magical acts of the system may be called spells, doing the work, laying a trick, conjuring, rooting, goofering someone. Despite these regionalisms these terms all generally refer to the same body of practices–that is the magical tradition.
