7.4.2 A comparison between relative and interrogative clauses

Finally by moving to the specifier of the CP, the wh-element is interpreted as an operator in both interrogative and relative clauses. The fact that one is interpreted more like a quantificational operator, like quantificational pronouns such as everyone or someone, while the other is interpreted like an anaphoric operator, which is referentially dependent on some other element in the sentence, like a reflexive pronoun such as himself, falls out due to the different functions of questions and relative clauses: one asks a question and the other modifies a noun.
