Abstract

This paper first defines the conditions under which copying and deletion processes are subsequential: specifically this is the case when the process is bounded in the right ways. Then, if we analyze metathesis as the composition of copying and deletion, it can be shown that the set of attested metathesis patterns fall into the subsequential or reverse subsequential classes. The implications of bounded copying are extended to partial reduplication, which is also shown to be either subsequential or reverse subsequential.
