The spatial dependence of modes in the shear AlfvÚn continuum on nonaxisymmetric toroidal magnetohydrodynamic plasma is investigated. As in configurations with plane or axial symmetry it is found that these modes may exhibit a singularity extended across whole "singular" magnetic surfaces. Nonaxisymmetry, however, changes the type of singularity from (in general) oscillating to (in general) logarithmic. If the nonaxisymmetry is too strong, the surface-covering property of the singular modes may be lost. Zero plasma pressure is assumed throughout.
