Non-binding restrictions on co-indexing of pronouns

Pronouns have no intrinsic referential meaning of their own, and in order to be interpreted they must be linked to a referential linguistic or discourse entity, and derive their reference by that link. Nowadays there is a wide agreement that syntactic factors, such as binding, play a prominent role in the distribution and interpretation of pronouns. Syntactic binding involves two conditions: c-command and coindexation.
