Non-restrictive (non-identifying or non- defining) relative clauses give interesting additional information which is not necessary to the meaning of the sentence. These clauses are put between commas.
Example:
Martin Luther king, who was known for his fight for the civil rights, was assassinated in 1968.
**Note:
In non-restrictive relative clauses:
1. who/which may not be replaced with that.
Example:
Jim, who we met yesterday, is very nice.
NOT
Jim, that we met yesterday, is very nice.
2. Object relative pronouns cannot be dropped.
Example:
Jim, who we met yesterday, is very nice.
NOT
Jim,we met yesterday, is very nice.
