Numeral constructions in Polish are known for their complex morpho-syntax: in particular, depending on the type, case and syntactic context, the numeral may show properties of the adjective or the noun. This volume presents a comprehensive analysis of these constructions set in the current generative-minimalist model of grammar, with elements of nano-syntax. The authors pay particular attention to a feature-based derivation of the numeral construction in its different versions, including complex multiplicative numerals, as well as its distribution in the clause. Numerals in the subject position, with their peculiar case and agreement features become a focal point of attention. Their properties receive a principled account through the use of the case projection sequence and disciplined movements within it.
