Where stress is demarcative (i.e., in languages with fixed stress), syllabification across word boundaries ought to be less likely than where stress is non-demarcative (i.e., in languages with lexical stress).
Standardized
Syllabification across word boundaries is likelier when stress is non-demarcative than when it is demarcative.
IF syllabification across word boundaries is possible, THEN stress is likely to be non-demarcative.
