Examines parallelisms between surface structure and logical structure and why those parallelisms do not extend farther than they do. If syntactic deep structures are identified with logical structures, an appropriate cyclic principle guarantees that cyclic rules will apply so that large-scale parallelisms exist between surface syntactic structures…

Divides Taiwanese modals into: (1) authority, where a deep structure agent exercises authority; (2) contigency, which concerns the speaker's judgment of the possibility or logical necessity df the occurrence of an event; and (3) volition, which expresses the subject's desires. The constructions in which these modals appear are examined. (PJM)
