Professor James Crippen (McGill) will be giving a presentation with the title “Optional ergative is subject focus in Tlingit.” Here is James’s abstract:

Tlingit has been described as having free word order (actually phrase order). This freedom crucially depends on the presence of -ch on a subject DP, a fact silently assumed in previous discussions. Without this -ch on the subject only SOV order is grammatical, implying that SOV is the basic word order in common with all other Na-Dene languages. The subject DP can have -ch but there is no distinct marking of object DPs so -ch has been described as ergative case. Since -ch need not occur, it appears to be an “optional ergative” as reported in a few other languages around the world. But case is not normally optional, and also -ch is always interpreted as focus on the subject which is unexpected for case marking. I argue that Tlingit -ch is not in fact ergative case, nor is it an indicator of the agent thematic role. Instead, -ch is the realization of a functional head in the left periphery that takes CP as its complement. The presence of -ch triggers movement of the subject DP out of the CP and up to FP. This analysis derives all non-SOV phrase orders as remnant movement to the peripheries driven by information structure. It also captures the apparent cataphora reported in earlier research, explains the disappearance of a- 3>3 agreement in some configurations with -ch, and the retention of a- for DP pronouns with -ch. Sentences where -ch appears on other phrases are the same lexical item merged as P selecting DP for instrument applicatives and CP for explanation clauses, both of which can cooccur with subject DP -ch.
