We present a syntactic account of the derivation of two types of attributivenominal compounds in Spanish, Russian and Greek. These include right-headed “root” compounds, which exhibit more “word”-like properties and single stress domains, and left-headed “semi-phrasal” compounds with more phrasal properties and independent stress domains for the two compound members. We propose that both compound structures are formed on a small clause predicate phrase, with their different properties derived from the merger of the predicate member of the small clause as a root or as a larger nominal unit with additional functional projections. The proposed structures provide an explanation of observed lexical integrity effects, as well as specific predicti...
