The main concern of the present study is to shed light on nominalization in English adopting nanosyntactic approach (Starke, 2009, 2011; Caha, 2011; Taraldsen, 2010). This paper analyzes the semanticosyntactic contribution of some selected deverbal nominalizers such as {-ing, -ation, -ment and -ism}. In addition, the researchers use Ramchand’s (2008) classification of verbs to get a profound understanding for the process of nominalization. It is hypothesized that the nouns formed by the deverbal nominalizers are the carriers of the semanticosyntactic features of verbal root. These features are atomic parts of the semantic features that are decomposed by split vP. The study finds that the noun formed by adding {-ing} has a hierarchical structure composed of three features: Case, process and Referential and as a result of Superset Principle it can lexicalize three structures: gerundive nominal that bears all three features, mixed nominal which has lost its case marking capability as a result of losing Case feature, and result/referential nominal that carries just one feature namely Referential.
