Potential vowel hiatus between words in Chicano Spanish is always resolved using one of several strategies, the choice among these strategies being influenced by several factors. One of these is the avoidance of adjacent segment identity, but complete identity appears not to be required: differences with respect to the feature [±high] are ignored in a specific set of cases. The analysis of these facts presented here supports the general proposal advanced by Bakovic (2005ab) that the avoidance of adjacent similar segments is due to the simultaneous satisfaction a constraint NO-LONG, which penalizes completely identical adjacent segments only, and other independently motivated constraints in the grammar.
