(This is kind of a follow-up on this post from last year.)
Speaking of McCarthy’s GLOW talk (related handout here): I got interested in an example of feeding discussed there. Ignoring melodic details, the two rules are:
Vowel Epenthesis: Ø –> V / #__CC
Consonant Epenthesis: Ø –> C / #__V
Interestingly, the generalization expressed by Vowel Epenthesis is rendered non-surface-apparent (opaque) by Consonant Epenthesis: the consonant cluster is no longer word-initial. In other words, Vowel Epenthesis appears to overapply. This is another example of an opaque feeding interaction, except in this case the right interaction is easily statable in OT (which is particularly interesting given that non-surface-apparent opacity is generally problematic for OT).
Is there some other way to state the rules that avoids this opaque feeding interaction? I can think of three basic alternatives. (more…)
