Seemingly idiosyncratic properties of Bare-NP Adverbials (BNAs), in fact, follow from assumptions supported on independent grounds. Lexical Restrictions and Typological Restrictions follow from the assumption that derivations of BNAs start with structures with abstract nominal heads, and Semantic Extension and Semantic Inclusion from the assumption that BNAs are theta-marked by their own nominal heads. Besides, predictions about possible types of BNAs are made cross-linguistically, based on the former assumption, and the long-standing problem of “Case-assignment” of BNAs is resolved, based on the latter assumption.
