THE UNERGATIVE/UNACCUSATIVE DISTINCTION IN POLISH The split of intransitive predicates into unergative and unaccusative (the so-called Unaccusative Hypothesis of Perlmutter 1978) is postulated, among others, for Dutch and German in Perlmutter 1978 and Hoekstra 1984, for Italian in Burzio 1986, for English in Levin and Rappaport Hovav 1995 and for Russian in Pesetsky 1982 and Babyonyshev 1996. The aim of the present paper is to argue that the intransitivity split characterizes predicates in Polish. The term "intransitive" refers here to intransitives proper (e.g. upasc 'to fall down') as well as to verbs occurring with the reflexive clitic sie (e.g. spoznic sie 'to come late'). Subjects of unaccusative verbs pattern syntactically together with objects of transitive verbs, while subjects of unergative verbs share many characteristics of subjects of transitive verbs. Various ways of representing the unaccusative/unergative distinction in syntax are compared (e.g. Burzio 1986 vs. Hale and Keyser 1993). A brief review is offered of tests proposed to identify unaccusative verbs in Dutch, English, Italian and Russian. These include, for instance, conjunction agreement, impersonal passivization, quantification by prefixed na- and po- verbs, unmarked word order, perfect/passive participle premodification and the genitive of negation test. The applicability of those tests in Polish is assessed. It is proposed that two diagnostics are particularly useful in identifying unaccusative verbs in Polish. These are the availability of the resultative -ly adjective and the ill-formedness of the -no/-to construction with an unaccusative verb, as exemplified in (1-3). (1) byc 'to be' upasc 'to fall down' dojrzec 'to ripen' zgnic 'to become putrid' umrzec 'to die' zsiwiec 'to grow grey' (2) *Byto/*Dojrzano/ *Umarto/?*Upadnieto/ ?*Zgnito/ ?*Zsiwiano '(They) were/ ripened/ died/ felldown/became-putrid/grew-grey.' (3) byly 'former' upadly 'fallen' dojrzaly 'ripe' zgnily 'putrid, rotten' umarly 'dead' zsiwialy 'that has grown grey' Then I investigate unaccusativity mismatches in Polish, i.e. instances when two or more unaccusativity diagnostics give contrary predictions. It is assumed, as in Levin and Rappaport Hovav 1995, that certain tests for unaccusativity are indicative of deep unaccusativity (e.g. the resultative adjective test, the impersonal construction) while others diagnose surface unaccusativity (e.g. quantification by na- and po- verbs). Furthermore, it is pointed out that a failure of a diagnostic test for unaccusativity does not necessarily signal the unergative status of a given Polish verb. The failure of an unaccusativity diagnostic may result from the existence of additional morphological or semantic restrictions on the construction in question (see Zaenen 1993). For example, verbs whose single participant denotes an inanimate participant are impossible in the -no/-to construction. Resultative -ly adjectives, on the other hand, are derived from telic and non-reflexive verbs. References Babyonyshev, M. 1996.
