ABSTRACT
The author discusses three sets of facts that seem to provide further support for the conclusion that the Head internal to a relative clause is indeed inherently indefinite. The first comes from the existence of languages that bear the indefinite character of the Head of restrictive relative clauses on their sleeves, so to speak. The second piece of evidence for the indefinite character of the Head of restrictive relatives comes from a number of constructions in Italian which contain a DP that can only be indefinite except when it heads a restrictive relative clause; in which case it is allowed to be definite. Therefore the third piece of evidence for the indefinite character of the Head of restrictive relatives comes from a reinterpretation, in the light of Cinque of the indefinite restriction of Lakhota internally headed relative clauses discussed in Williamson.
