A decomposition of the ``rooted'' fermion effective action into Wilson fermions and a nonlocal, lattice spacing suppressed functional is presented, complete with link interactions. Some proposals are given for analytical, nonperturbative studies of the fourth-root trick.9 pages, substantial revisionHigh Energy Physics - Latticetext
