Just as there are ways to transform syntactic structures to prosodic structures (e.g. Abney 1992), prosodic structures can also provide clues to syntactic structures. As we have discovered, ... turn to prosodic structures that can be adjusted to correspond to syntactic structures. They usually involve the use of function words such as conjunctions, prepositions and determiners. Syntactically,...
