Number agreement in Russian predicates

Abstract

Russian shows the mixed agreement with the polite pronoun vy and pluralia tantum nouns, both of which have plural number in form but either singular or plural number in meaning. Two different forms of adjectives – short form and long form – agree in different number with those number mismatch nominals.

I adopted the idea of Siegel (1976) etc. that when a long-form adjective appears in the predicate position, there is always a null head that it modifies, with the HPSG's agreement theory of Wechsler & Zlatic (2003). I propose that all predicates – verbs, SF and LF adjectives – except predicate nominals show CONCORD agreement. LF adjectives show CONC agreement with the null anaphor 'one'. The different number values of LF adjectives results from index agreement between the null anaphor and the subject of the sentence.
