|Our paper has two purposes. The first is to propose a three-headed, "ditransitive" structure for the projections of Speech Act. The second is to designate the five politeness morphemes in Japanese as representing one of the three heads of the ditransitive structure we propose. We argue that the causal politeness morpheme -ssu represents the highest Speech Act head; the non-verbal politeness -desu represents the middle Speech Act head; the non-verbal politeness morpheme -desita, and the verbal politeness morphemes -masu and -masita represent the lowest Speech Act head. We discuss a few consequences of our analysis in regard to the relative size of the three Speech Act projections. Also discussed is the distinctive speaker-hear relation characteristic of the use of the casual politeness morpheme -ssu. Syntactic structure must exist beyond the Speech Act projections, given our characterization of -ssu as the topmost Speech Act head.
