The paper explores the relativization mechanisms in Romblomanon, and how these relativized sentences are embedded to another sentence to form a complex construction. The first part introduces the language and the depth of the studies made regarding Romblomanon and complex sentence formation in general. This is followed by a discussion of the noun phrase to which a relative clause will substitute in a matrix sentence. The third part thoroughly defines the basic sentence in Romblomanon. The next sections are devoted to relativization, embedding relative clauses, and discussing the “headless” relative clauses.
