The constraint ALL-FT-RIGHT must also rank above WSP in order to account for the possible occurrences of unstressed heavy syllables in pretonic positions, such as /piskaubu-av/ [pis.kaw.(bwav)].(14) If ALL-FT-RIGHT is dominated by WSP, [pis.kaw .(bwav)] would incorrectly lose to *[pi[??].(kaw).(bwav)].
(14.) In addition, to account for the fact that [pi[??]kaw(bwav)] is more optimal than *[pi[??](kawbwav)], we seem to need a separate higher-ranked WSP constraint, which prohibits only heavy syllables in the nonhead position of a foot but not those unstressed heavy syllables that are linked directly to the Prosodic Word node.
