|Title:||Headed Spans and Autosegmental Spreading|
|Authors:||John J. McCarthy|
|Abstract:||When Optimality Theory (Prince and Smolensky 1993) is applied to autosegmental phonology (Goldsmith 1976), markedness constraints that favor autosegmental spreading are required. The pro-spreading markedness constraints in the current literature have typological
problems: they undergenerate because they do not favor partial spreading (McCarthy 2003), or they overgenerate because they can favor unattested alternations, such as 'spreading' by blocking epenthesis (Wilson 2003).
This article proposes a modification of autosegmental representation that is intended to adddress these problems.
