Rule reminder
The resumptive clitic in a dislocation must match the grammatical role of the dislocated element: direct object → lo/la/li/le; indirect object → gli/le/ci/vi; locative → ci/vi; partitive/prepositional (di) → ne. Getting the right clitic is essential for grammatically correct dislocation.
