Looking for some descriptive help for a language description project. Stress assignment in the language is fairly complex and pretty resistant to easy generalizations, although prominence is calculated somehow based on syllable weight. In verbs, where a verb root mostly always takes multiple prefixes and suffixes, phonological processes conspire to make sure that the root is a heavy syllable, either by making sure it maintains a coda or by lengthening its vowel. I'm familiar with some treatments of English stress that maintain lexical stress on the roots of morphologically transparent latinate lexical items, but I am wondering if anyone here is familiar with terminology or work relating to phonological processes which work on a principle like "the root must take primary stress" or "the root must be a heavy syllable".
Thanks
