PHONOLOGY: a branching representation of stress, introduced by Liberman & Prince (1977), see also metrical phonology. A metrical tree is a hierarchy in which syllables are combined into feet and feet into a word constituent. Higher level structure includes the phonological phrase, intonational phrase and utterance (cf. Selkirk (1981), Nespor & Vogel (1986)). Pairs of sister nodes are labeled Weak-Strong or Strong-Weak (or by the Lexical Category Prominence Rule). The English phrase achromatic lens is represented as follows:
/ \ / \ / \ / \ w s / \ | where S = syllable, w = weak Fw Fs F F = foot, s = strong / \ / \ \ Ss Sw Ss Sw S | | | | | a chro ma tic lensHayes (1981) constrained metrical theory considerably by the introduction of a universally defined set of parameters that characterize the stress systems of languages (i.e. bounded/unbounded; dominance (left/right), direction of footing, quantity-(in)sensitivity).
