Primitive Optimality Theory (OTP) <cite>(Eisner, 1997a)</cite> , and extensions to it (e.g., Albro (1998) ), can be useful as a formal system in which phonological analyses can be implemented and evaluated. However, for certain types of constraints, translation into the primitives of OTP (Eisner (1997b) ) can only be accomplished by adding to the grammar a number of ad hoc phonological tiers.
