The Puzzle of Case Agreement between Numeral Phrases and Predicative Adjectives in Polish

The paper addresses the optionality of case agreement between a numeral phrase in the subject position and its modifying or predicating adjectives in Polish: such adjectives either agree with the numeral or - apparently - reach into the numeral phrase and agree with the noun phrase within it. While previous analyses of this phenomenon postulated special agreement mechanisms, we account for the troublesome facts by assimilating Polish numeral phrases to coordinate structures.
