There are two conceivable PSG-based analyses for a Japanese sentence like "Hanako-ga kawa-e, Masao-ga yama-e itta (Hanako-NOM river-to, Masao-NOM mountain-to go-PAST)," namely an analysis in which such a sentence is generated by right-node-raising the tensed verb ("itta (go-PAST)" in the example above) out of two conjoined tensed clauses and another analysis in which such a sentence is generated by right-node-raising the verb stem ("ik- (go)" in the example above) out of two conjoined tenseless clauses and in which the tense morpheme ("-ta (PAST)" in the above example) is taken to be outside the coordinate structure. In this paper, we argue that there are sentences for which the former is the only possible analysis as well as sentences for which the latter is the only possible analysis.
