Syncretisms involving clusivity
The inclusive and exclusive are commonly considered to be kinds of the first person plural. In this chapter, I will investigate whether they deserve this name by looking at syncretisms between clusivity and other person markers. Such syncretisms are rare, but a thorough investigation has resulted in a large enough sample to allow for some conclusions. The result is that the exclusive is often syncretic with the first person singular, and can thus indeed be considered a kind of first person plural. In contrast, the inclusive cannot. Further, the often claimed link between inclusive and second person in spurious. This claim probably only arose because of selected attention for those syncretisms arguing for such a connection, but disregarding all other syncretisms that argue against it. In this survey, all possible syncretisms are considered resulting in the observation that the inclusive/second person syncretism does not occur more often than others.

Verb agreement in Proto-Tibeto-Burman
My purpose in this paper is to outline a preliminary reconstruction scheme for the agreement morphology of the Proto-Tibeto-Burman (PTB) verb. I will deal with two separable issues: the provenence of the widespread suffixal agreement paradigm, and that of a less widely attested set of prefixes. The suffixal paradigm has, since the work of Bauman (1974, 1975, 1979, see also DeLancey 1980, 1981b) been recognized by some, but by no means all, Tibeto- Burmanists as being reconstructible for PTB. The prefixes, on the other hand, are as far as I know currently universally viewed as of secondary origin (although Bauman (1975) attributes a PTB provenence to one of the morphemes involved, he does not consider it to have been part of an original agreement system). I will show, however, that there is good evidence on which to base an argument that these also are of PTB provenence, and in fact very likely older than the suffixes.
