The article explores different types of relative clauses in Spanish, focusing on constructions without explicit antecedents. It distinguishes between clauses with implied antecedents and those without any antecedent at all. The study also looks at clauses introduced by "quien" without a stated antecedent, as well as infinitive clauses with no expressed antecedent. The researchers analyze examples and discuss the general validity of the rules applied to relative clauses in Spanish. The main goal is to understand how these constructions work in the language and their theoretical implications.
