Transitivity and Causation in Lushootseed Morphology

1996

The morphology of Lushootseed, a Salishan language spoken in the Puget Sound area of Washington State, is notable for its extensive use of a set of verbal suffixes which affect both their valency and the syntactic roles taken by the NP arguments of the stem to which they are attached. Stems without affixes are inherently stative and intransitive, while verbs designating events are derived by means of affixes, some of which introduce one or, in some cases, two additional actants, thereby effecting an increase in valency. Hess (1993a) divides these affixes into two classes, patient-and agent-orienting, depending on the semantic role (agent/experiencer or patient/goal) filled by an overt third person NP associated with the verb bearing the suffix. For example, 1 (1) ( a ) Patient-oriented ˙u+g"\ç© +\d tsi ç© aç© as [pnt]+look·for+[patient] Dƒ child '[he/she] looked for the girl' 2 (Hess 1993a: 44) (b) Agent-oriented ˙u+g"\ç© +\b tsi ç© aç© as [pnt]+look·for+[agent] Dƒ child 'the girl looked for [him/her]' (Hess 1993a: 9) In both of these sentences an event participant has been elided. The first sentence has an elided agent-the syntactic subject, whose identity would be unambiguous in discourse-that has been removed by a rule in Lushootseed (discussed in more detail below) that prevents the expression of two overt NP direct actants (subject or direct object) in a clause; the NP following the verb expresses the goal of the action, the direct object, which is licensed by the patient-orienting suffix -t (which surfaces as [-\d]). 3 In (1b), on the other hand, the NP is both the agent of the event and syntactic subject and is licensed by the appearance of the morpheme -b, while the (1996).
