Lexical category prominence

PHONOLOGY: a labeling rule proposed in Liberman & Prince (1977) to provide the nodes of a metrical tree (metrical phonology) with labels strong or weak expressing prominence in systems where uniform sw- or ws-labeling fails. It labels higher level constituents (i.e. feet (=F)) that consist of syllables. The main part of this labeling rule in English states that in a configuration [A B], B is labeled strong if and only if it branches. EXAMPLE: Compare the following examples:

    / \             / \
  Fs  Fw	   Fw  Fs
  /\   |          / \  /\
 s  w  |   	 s   w s w
 |  |  |         |   | | |
húrricàne	 àchromátic
The final foot of hurricane is labeled weak since it does not branch, while the final foot of achromatic is labeled strong since it branches.
