Example

[main clause]	[conjunction]	[main clause]

Non-restrictive relative clause

Provides extra information that could be left out without affecting the meaning or structure of the sentence. They are normally introduced by which, whose, who, or whom, but never by that. You should place a comma in front of them.

[main clause]	[non-restrictive relative clause]
