Does binding theory occur in syntax or semantics?
Personally, I think the index of the pronouns is semantic because who it refers to is interpreted in the meaning, which should be regarded as semantic.
However, I still think that we should not ignore the syntax playing a significant role for sure.
I have read that the traditional binding theory is syntactic while Reinhart's approach predicate-argument is kind of semantic. What is the nature of the pronoun then?
