With defining relative clauses, there is a different word order according to the status of the relative pronoun in the sentence (that is, it can be either the subject or the object of the relative clause).
The relative pronoun is the subject. The word order is --> subject + verb + object
The relative pronoun is the object. The word order is --> object + subject + verb
Does this rule apply to the non-defining relative clauses as well? Or is there any other rule to follow?
