Luigi Burzio's Principles of English Stress challenges many of the assumptions that have underpinned the generative description of English stress and more generally 'standard' metrical theory. Central to Burzio's analysis is a novel typology of metrical constituents that includes ternary feet and excludes monosyllabic feet. The analysis is essentially nonderivational in character: principles of well-formedness check for the presence of stress and weight in the output. The principles themselves are organized into a hierarchy consisting of a hardcore-controlling foot form that in cases of conflict may override principles of metrical consistency and alignment of edges. The interplay among these competing principles accounts for the cyclic effects of the standard theory. A special role is accorded phonetically null syllables that analyse hidden metrical structure to preserve a simple foot inventory and sharply curtail the standard theory's extrametricality.
