Abstract
In Pesh (ISO 639-3 pay; Honduras, Chibchan), arguments show interesting patterns of differential
case marking. While arguments are expressed more frequently without a case marker (87%), in this paper my goal is to
explore the conditions under which an argument is flagged with case marking. The absence or presence of case marking
cannot be explained by morphological or syntactic environments. Based on a corpus annotated according to Givón’s
method (1983, 1994), which
focuses on accessibility and topic continuity, I show that the majority of arguments that are case-marked have given
and persistent referents, contrary to what certain authors write about the lighter encoding of a given referent (Chafe 1976, Givón 1983, Krifka 2008). The motivation for this heavier expression is the
contrastiveness of the referent. I show how the unexpected combination of givenness and contrastiveness constitute in
Pesh given referents which may indicate an alternative, exclude other alternatives, or highlight surprising
information. At information structure level, they consist of a topic that contains a focus, which is doing what focus
always does, namely indicating an alternative. Case marking in Pesh is motivated by contrastiveness, whether the
referent is given (62.3%) or new (32.8%). The characteristic that distinguishes given and new referents is the degree
of continuity of the referent in relation to the following context of the discourse. Most often, given referents are
marked by the ergative case or the absolutive case when they are persistent, while new referents are case-marked when
they are used to introduce unexpected or surprising information involved in an important event at some specific
moment. These contrastive referents are almost all non-persistent in the clauses following their mention. The other
occurrences of case marking (4.9%) are motivated by the discriminative function, to avoid a possible ambiguity between
A and other participants of an event.
